We are not getting the expected performance from Barcelona because of some weaknesses in defense and midfield. They dropped points against Bayern and Inter in the Champions League due to defensive weaknesses and mistakes. Xavi is more focused on his attack and he has strengthened his attack. But Barcelona's defense is still weak. If the defense is not strong, Barcelona will not be champions of La Liga. Barcelona management will probably focus on strengthening their defense in the winter transfer window.
Barcelona frontlines is very incredible and they have put numerous goals in their opponents net but they still have issues with their defendlines and problem in the midfield. Xavi should make speedy amendment and good lineups in his squad if he still wants to win games. Let him start the right players like Frankie de jong who have the strength to play in the Midfield, he should be considered a starter. Their defend line have really costs them to concede more goals against teams in the UEFEA and also one of the major errors that leads to them to losing to Real madrid in the El Classico. The defenders are making ter Stegan looking like a flop in champions league games and we all know ter Stegan have been outstanding this season. Barça president, Laporta would make good signings in January transfer window.
