i think Barcelona could be one of the teams that become more active during the winter transfer period. With Gavi being out for a long time and also knowing that Lewandowski could drop out because of an injury again since he is not the youngest player anymore, it could make sense for them to be careful and do something about the depth of their squad. They can't just buy any player, but if there is an opportunity to add some quality even if it is only temporary like a loan player, it should be done I think. There are a lot of games ahead of them in the next few months.
Barcelona will crumbled this season due to the intermediate injuries in the club, there's a whole lot of injuries that hits harder especially on the big players this season. Perhapes Xavi Hernandez is working entirely on bringing the best out of his players, he's patient ands setting extreme rules to help him elevate and boost team's performance without the presence of these important players. Gavi is ruled out for a long term, and the returning players that have not gain full fitness will try to adapt quickly because there's a whole heavy burden on the team.
Barcelona is in a state that might drop the club's performance due to the present suitaution of Gavi and Lewandoski. Those are key players because at this time Barcelona needs to be winning matches if they want to still remain in the competition for the title. Xavi should think of a way to manage the players on ground and use them to win matches so that they wouldn't feel the absence of Gavi and Lewadoski who is getting weak. U believe that Barcelona will be able to overcome this challenge but they need to really work hard.
