Barcelona president Laporta said that they weren't going to be in a condition that they could sign any new player in the transfer window in January according to some news. I don't see this as bad news for Barcelona truthfully. Because Barcelona are already in no need of strengthening their squad in the middle of the season. They already have a great squad quality full of talented youngsters and experienced players like Lewandowski. Their problem on defeating big teams now is not related to the squad quality.
It is related to making the right decisions for these matches in terms of not only the player choices but also the strategies. It is in Xavi's hands to fix their problems against big teams. Because it has cost them big so far like being eliminated in the Champions League.
The problem Barcelona is facing is not the quality of the players or their poor performance, this season Barcelona has performed well after bringing in several experienced players. The arrival of Kounde has made Barcelona's defense stronger, Kounde immediately adapted well and was able to partner perfectly with Araujo.
Improving Balde performance has also benefited Barcelona. This Wonderkid who graduated from La Masia always looks good when given minutes to play. Apart from having made it into the main squad, he is also able to play in two sectors at the same time as left back and right back.
The three midfielders who are always filled with talented young players have made many changes in Barcelona form of play, De Jong, Pedri and Gavi have made Barcelona midfield more solid and able to control the game well.
There is no need to doubt the attack line filled with Lewandowski, Barcelona could easily have looked for the winning goal when Lewandowski got the ball.
Barcelona only weakness this season is difficulty winning when facing big teams, Xavi must find the best strategy to achieve his goals this season, including being able to keep up with teams that are on par with the Barcelona squad.
