In my oppinion he left because Bayern is the new best team in the world and Barca is no more .
Your opinion on this comparison is quite trendy right now, and even all Barca fans agree BM deserved the trophy last year. However, you may recall that Messi and Busquets were hurt? Barca had and has superb backups at most positions, but at CF and DM the second string is a big step down. Messi and Busquets playing while injured are not all that good.
Right now, I think if you asked most managers which team they would select if they had the choice, the answer would be Barca. You can't even put a price on Messi. Neymar sold for the highest price of any player sold this year, and he still has to prove he is even the second best player on this team.
Have you agree with ya there
Barca's success against counter attacking teams like bayern and RM depends heavily on the CB and DM being in their best forms. In the case of CL against bayern Pique, Mas, Sergio, were either injured or out of form as a result it was not a fair
game to call for a decline of Barca's dominance. However, if the board is stupid enough to not shell out money on at least one solid CB before the window closes it could be a major issue for us especially latter half of next season.
