Hansi Flick will have difficulty to improve Barcelona defense if he wants to gain success with Barcelona. If he fails to improve defense system for Barcelona, there is very small chance of success there. Furthermore, attacking power of Barcelona was affected a lot last season with decreasing performance of Lewandowski because of ageing. Ageing effect on Robert Lewandowski can become bigger in a new season and this bring another big difficulty to Hansi Flick.
For Hansi Flick to accept the offer of becoming Barcelona coach, I believe he is ready to face the challenge brought before him about the financial downgrading of the Barcelona team to sign new quality players, to make use of the currently available players to win matches and to top the laliga league table but not to win the trophy.
I think Hamsi Flick has a big task ahead of him to fix in Barcelona, to keep the players fit and give them the courage that they can get to the top of the table once again with Him not with Xavi, despite the change of new manager with new football tactics and new players signed
As a coach with sufficient experience, Hansi Flick knows very well the obstacles when he was appointed as a tactician for the Barcelona team. I had read several newspapers, before Flick started handling Barcelona he wanted to know more about the situation and management of Barcelona. So, Flick realized that Barcelona's condition was not healthy. which means, he will experience various obstacles either in signing players or non-technical problems for example. which in the end Hansi Flick also reviewed the players from the La Masia academy, at least he was looking for player options that could be brought to the main team to enter his squad in La Liga. proven, Barcelona is again rumored with its financial problems to bring in several names in the summer transfer window this. although several famous journalists always report Barca with the names of players who are soaring, but there have been no concrete steps they have taken in this transfer window. I mean, the players they are targeting are really brought to Camp Nou. with the news that is developing now, I am quite sure that Flick has no choice but to start working with or without bringing in the players he is looking for. the point is, Hansi Flick certainly has a target and mission to bring Barcelona better than the previous season. in his first season handling Barcelona will certainly go through tough challenges, but he is a coach with long experience. related to the Barcelona squad and its decline, whether in the front line or defense, he knows what he has to do. moreover, Barcelona has only played one friendly match. we cannot measure his performance yet, especially in the pre-season match is not a real campaign.
