I agree. Xavi already made Barca looked a powerful force once again and winning LaLiga is for sure a great achievement for the club but especially for the fans who have wait quite a lot to see Barca lifting a trophy once again.
Maybe next year , City will face Barca as UCL champions and Pep vs Xavi should be the game of the year most likely because I do see City winning UCL this year but I also see Barcelona being a force in UCL next year too.
Congratulations Barcelona you have confirmed the La Liga champion. Actually, I don't support you, but La Liga belongs to you this season. With the shopping you spend, it should be more next season than today. Barcelona should be able to play better and be in the UCL until the Final. At least the arrival of Xavi this season got good results. But they haven't been able to play well in Europe. Next season I hope Real Madrid will win La Liga.
People constantly try to undermine the work that Barcelona has done so far in a very short period since they started their rebuilding process. During the last summer transfer window everybody laughed at Barcelona and concluded they couldn't sign a single player, but they were proved wrong. Some English pundits, sports websites, and newspapers even said Barcelona has gone bankrupt and would be sold or something and a lot of football fans ran with this. Here is Barcelona today standing as La Liga champions and now you are pinning it down on the signings they made and saying they should be in the champions league final with those signings.
While I agree with you that Barcelona should have done better in Europe, I also have to remind you that teams like Chelsea and even Nottingham Forest spent more money than Barcelona yet they both won't be qualifying for the UEFA Conference league, talk more about the champions league.
Barcelona has been run better since the new management took over and it's crystal clear that the club has a future.
They may not win the champions league next season or the season after that, but you can see that they are on the right track to be a top club in Europe again.
