Meanwhile, for the Barcelona team, which is currently in great difficulty and also lacks players, of course this is quite a loss, and Xavi, the Barcelona coach, must work even harder in arranging tactics with the available players so that the team's performance is maintained.
I think Xavi will continue to play the remaining players currently available in the main squad even though maybe later Xavi will have to look for a replacement, but it takes careful thought to find the right player to replace Gavi after a serious injury, of course this is very detrimental to Barcelona especially considering they still playing in the UCL and also maintaining their position in Laliga.
Barcelona must continue to consistently be on the winning track to remain at the top of the standings in order to be able to hunt for the title this season by taking advantage of the failures that Girona or Madrid might make at the end of the season. Barcelona must be able to play with players from the existing main squad and of course they will probably there are slight changes due to Gavi's injury in the main squad. I think Xavi has thought about everything and knows how to handle this situation.
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.
