Losing players to injuries has always been a problem to every team. Losing seven first team player is a lot of numbers which definitely affect the team Xavi will have to do squad rotation to corb this problem. Playing Madrid at this time will be a tough one to handle especially when most of the injured players are defensive playings and playing against a very good attacking team it will really be tough for Barcelona.
It's true, losing a lot of players is definitely a problem and even though they won in La Liga in their last 2 matches but their score really feels the difference when often seeing at the start Barcelona score very well at least 2 goals in every game and now the gap feels according to I.
Fortunately Xavi can still play well and still bring points even though maybe for the Champions League it is still a little worrying for them.
