Injury has put Barcelona in a poor form recently, we see how they lost their match today against Getafe. There have begin to lose points,but I don't thing that it will be possible for Real Madrid to catch up with them on the league.
I just hope that with this their present form they would be able to win few matches not only draws or loses,if not it will not tell good about Xavi. Barcelona played better than Gadef but Getafe didn't give them the opportunity to net the post.
Getafe played very defensively at home today, so of course that has made it difficult for Barcelona to score goals. Lewandowski had several chances, so did Raphinha and several other players, but they were countered by the good performance of Getafe goalkeeper, Soria. I agree that injury problems meant that Xavi had to rely on a few subs to play an active part in the game. Pedri, Dembele and De Jong are still injured and of course that comes at a cost when the rest of the players are not at their best.
So far Barcelona have not scored a single goal in 3 consecutive matches including the second leg of the Copa Del Rey semi-final against Real Madrid. Their goalscoring faucet seems locked, so of course that leaves the Barcelona manager struggling to come up with a solution. La Liga is getting closer to the end, but if Xavi is still struggling to find solutions then I think his chances winning of title will be even lower.
