Being a coach is totally different when he was playing as a player. So many critics have been coming for him early season caused by he has the worst history with barcelona. Xavi has worst win rate compared with another coach of barcelona in the same era. There shall not be a rotation when it will be only making the performance from the club to decline. The problem is MU was on fire. Manchester city as a strongest candidate in UCL has beaten by united. It was showing us about how strong MU right now.
Barcelona needs also become very careful. MU has a very good defenders right now and MU is has been found its soul. It can be said that MU has a very good team work now.
Both clubs are going into the head-to-head match in great spirits - Barcelona in first place in La Liga and United just one point behind City. It will be most offensive if some of the clubs (for example, United) treat the game not as an important event, but as a second or third priority. There are fewer such suspicions about Barcelona because Xavi, after a series of failures, is trying to win at least something.
