Barcelona are on fire, Chelsea are calm as ice, and the two most perfect club teams in the world today will clash tomorrow evening, with only one of them making it to the last eight of the Champions League.

Between these two giants, which side to support actually represents a choice of football philosophy.

Barcelona has never known what it means to be conservative, and plays the world with unrestrained and smooth attacking football, and its representative is Ronaldo Jr., a genius who looks like Maradona.

Chelsea have never been emotional, relying on concrete defence as their foundation, and at the heart of their player is John Terry, a Baresi-esque steel defender who has been a leader at a young age.

The first leg between the two sides was definitely a typical collision of the two styles, with Barcelona's continuous attack and finally achieving a comeback after conceding the first goal, and Chelsea had one less man at the back to make the opponent only win twice with 24 shots, making enough money for the second leg to turn the tables.

With 24 shots on goal to 2, it's hard to imagine a contest between the two giants, with Barcelona making the most of their attacking advantage but giving their opponents a gold-dollar away goal in a situation where they only had two shots on goal and all went off the rails, while Chelsea were awkward but well-organised.

In addition, it is commendable that Chelsea coach Jose Mourinho has not hesitated to put on an iron bucket formation at the expense of his notoriety of conservative football, and his eclectic and unique style can be called an alternative to big-name coaches.

The injury situation ahead of the second leg between the two sides was also interesting, with Barcelona losing the only midfielder in midfield who did the dirty work. Chelsea, who have been stronger defensively than attacking, have lost the most creative and lethal Arjen Robben in the team, and some data show that the quality of Barcelona's defence without Marquez has been greatly affected. And Chelsea's attack before and after Robben's two absences was simply two grades, which means that before the game started, the two giants showed signs of becoming more and more extreme in terms of technical and tactical deficiencies.

With a 2-1 defeat in the first leg, Chelsea must win this game to progress, and the world's best defence alone is not enough, while a 1-0 defeat for Barcelona would be a death sentence. Only an attack on the rivers and lakes will not ensure safety.

The two giants must come up with their own weaknesses to compete to see whose shortcomings are worse, and the dialogue between the strong and the strong evolves into a contest between the weak and the weak. It casts a layer of mystery over the game.

Before tomorrow's game even begins, the two managers are already engaged in psychological warfare, with Jose Mourinho and Rijkaard both focused on one man, Chelsea's Dutch midfielder Arjen Robben.

Mourinho said it publicly. The team's main midfielder. Dutch talent Arjen Robben will not be in the starting line-up tomorrow due to injury, and he may not even be on the bench.

However, Rijkaard expressed a diametrically opposed view, and when asked by reporters what he thought of Chelsea's tactical arrangements, Rijkaard replied: "Chelsea? First: Reuben. Second: Reuben. Third: Reuben. 'Obviously the Dutch boss thinks his compatriot will play a very important role in tomorrow's game.

Barcelona won 2-1 at the Camp Nou in the first leg of the match between the two teams, having trailed 1-0 to England in the first half. Mourinho declared that at half-time. Rijkaard had put pressure on the referee on duty, Swede Frisk, which led directly to Drogba's red card. After that, Barcelona took advantage of the numerical advantage to win the game.

Rijkaard was furious and flatly denied the claim, saying: "Mourinho's accusations against me are completely wrong, I don't want to comment more on this matter, I hope UEFA will look into it." ”

Jose Mourinho even wanted Rijkaard to speak publicly to the media at his pre-match press conference today, and Rijkaard expressed his displeasure, saying: "Maybe he [Mourinho] wants to use the media to beat me. ”

Mourinho condemned the Dutchman's behaviour of "putting pressure on the referee", as did the Dutchman criticise the Portuguese's conservatism. The Blues were very conservative in the first leg, with Chelsea, who started as defenders, without a single decent goal in the game, with the only goal coming from an own goal from the Barcelona defender.

Barca's players have also expressed disdain for the English's conservatism, with Puyol, Ronaldinho and Van Bronckhorst all expressing dissatisfaction with the Englishman's tactics, and the new Footballer of the Year Ronaldo even believes that Barca will definitely win the matchup.

Rijkaard hit back at Mourinho saying: 'These two teams have completely different tactical styles, Chelsea have only one goal, which is to win, the three points are above all else, Barcelona is different, of course the team needs to win, but the team also needs to give those season package owners more satisfaction, we need to play a good game"

'Chelsea's attack is very lethal, but most of the time their tactics are defensive counter-attacks.

"It's a tough fight for both sides, but I know it's a tournament that any professional athlete dreams of."

In this game, Barcelona will miss the captain of the Mexican national team, Rafael Marquez, who has been very consistent this season, who went off injured in the previous La Liga competition. The Mexican, who has been used as a midfielder for most of the season, has been one of Rijkaard's discoveries this season, and he has been significantly tougher than other Barcelona midfielders, and he has done a good job of filling the void since Davies' departure, and his midfield interceptions and organisation have been very effective.

In this game, Oleger will be in the central defensive position, and he will replace Marquez. Former AC Milan champion Albertini and Spanish native Gerard will be present in Barca's midfield position in order to deal with the Englishman's high-altitude ball tactics, but Albertini's ageing and Gerrard's recklessness have people worried.

Dutchman Van Bronckhorst, a former Arsenal player in the Premier League, will play at his familiar left-back position, and he will form a wing on the left flank with Ronaldo. As the tournament approached, the Dutchman said: "Everyone thinks it's the most evenly matched game of the Champions League and we hope the Englishman can play better in this game." ”

'I hope they can attack more because they need to win the game and therefore they have to score as well.'

'We created a lot of chances in the first leg at Camp Nou, but unfortunately we didn't convert them into more goals and we have to try to do better this time.'

Regardless of Rijkaard's response to Mourinho's comments, how much Barcelona were led by the nose by Chelsea.

What Mourinho said, Barcelona could only passively return the favor.

All forgets that Jonker was the striker who started the game, and Mourinho repeatedly downplayed the impact of Jonker's start, and no one noticed that it was a smokescreen that the Chelsea boss once again used to the opponent.

The two of you come and go, Chelsea avoid many things that they don't want everyone to pay attention to, but Barcelona can't do this, the two are good at psychological warfare, and they make judgments.

Rijkaard, who was born as a professional player, may know that there is something wrong with the road and deliberately avoid it, but Mourinho will not let the opponent get his wish, and in the psychological warfare contest before the game, I have to say that the Portuguese young coach came to England is really the right one.

Ferguson is the best teacher, I don't know what Mourinho learned from the old man Socrates, but on the surface, after coming to the Premier League, Mourinho is indeed better at psychological offensive than before.

Joan Ke is happy to be relaxed, and a lot of the media are attracted to the head coach, so he doesn't have to waste his tongue in front of the media before the tournament, and he can concentrate on training, which is definitely a good thing. (To be continued......)
