Barcelona was already a famous team. He didn't become a famous team with Xavi. It made people wonder if he could catch up with his past successes with Xavi. Barcelona's history is full of great achievements. They had great years, especially with Ronaldinho and Messi. In recent years, they are not what they used to be, but this situation may gradually change.
Xavi was able to get Barcelona back on track because before he joined the team, the impact of the financial crisis was very strong. Thanks to discipline, he managed to return good results, retain players and replenish the team with new players. Yes, Barcelona used to have Messi, but now they have Lewandowski and Gundogan, if that's not enough then I'm sure Xavi will be able to strengthen the team even more.
So far, Xavi Hernandez has actually been able to make Barcelona better than the previous few seasons, but this season, the wins they have won are not very convincing this season, but A win is still a win no matter what, but they have to start thinking about being better because it is getting worse, the day of the competition will be increasingly difficult and if they want to defend their title again then staying on a winning track is a must otherwise they will experience high difficulties in fighting for the title.
Yes, they have Lewandowski, and this season there is İlkay Gündoğan who is one of the key players for the success of Manchester City, Gündoğan is expected to perform brilliantly in his first season with Barcelona as he always showed when he was with Manchester City if in the next matches, Barcelona appear more impressive then Real Madrid will face a tough challenge from this club in title race.
