Barcelona seems to have things in order now. To win 0-3 at Sevilla, few clubs do. They have, of course, brought in several players. In recent years they have actually spent a lot more money than last year, so I think it's all the more clever that they are doing so well now. This Barcelona is better than the Barcelona of the last 3 years. Also thanks to Koeman who has little understanding of coaching and has made several bad buys. Barcelona and Real Madrid will compete for the championship together. Everyone is looking forward to the match between Barcelona and Real Madrid, a match that I think could go either way. 0-4 it will not be like last year. and neither is 4-0.
You are right,Barcelona have changed it shape under Xavi,the club and the players are doing so well that one begins to imagine them win the Lalliga and probably do very well in the champions league this season.Last season,it was Madrid that won the Champions league and the Lalliga,perhaps the tittle might still be at Spain,maybe Barcelona will win it this time around.
Nevertheless,I'm not too sure because we have other good teams like Mancity,Bayern and PSG,that we can call strong tittle contenders for the Champions league trophy.
