Barcelona are in dire straits right now. Despite winning the first home match against Plzen, they lost their next two away matches against Bayern Munich and Inter Milan. They managed to win only one out of three matches. Now going to the next round is completely uncertain for Barcelona. Barcelona will need to win both home matches against Munich and Inter Milan if they are to qualify for the next round. If they do not win the next three matches, it is almost impossible for Barcelona to go to the knockout round. Despite having such a strong squad, Barcelona's poor performance is very disappointing.
Barca did poorly in the UCL, but they had a good performance in La Liga. I don't know if this is a tactic from Xavi, but it looks like Barca is overwhelmed to face a team that is in the same group as him.
if Barca wants to qualify for the next phase, I think Barca must turn things around from Barca's previous matches with Munich and Inter. Winning the match with these two teams will certainly be quite difficult for Barca. although they have a more solid team at the moment, Barca still has to work hard.
