I think the problem why never have success forward on Barcelona right now because depending with midfielder position, last several season Barcelona have great midfielder like Iniesta, Xavi, Raktic and Vidal looks easy for forward how to make many goal each season. But now almost forward looks not easy how to scoring on every match and depend with Barcelona goal in this season where each match just score one or two goal only. Need looking for new midfielder position because with De Jong only is not enough how to give assist for forward.
It's about the whole, because for me the important role in football is for all players and not just about a few players from a few lines. Even though Barcelona again have good midfielders but attackers always make poor finishing, then a great midfielder is not enough. So yes, basically Barcelona is like a team that is starting over from scratch, so the process will certainly go through and even though the total goals obtained this season are not as good as the previous seasons. But Xavi, who has at least managed to improve Barcelona to 5th place, at least it has become a good achievement when the team's condition is not good.
This Barcelona squad will need at least 2 more years to get in shape and in the situation to be on the top tier teams in Europe. But at the moment, they are a lower A-tier team I have to say.
But I have to admire Xavi with how well he has done with the huge duty on his shoulders. Even at a time, Barca weren't even top 10. But now they are 5th placed and the influence of him on the squad is visible. I'd say that give this team time, and Xavi some more time, and Barcelona will turn around.
