Xavi was the best coach Barcelona could ever have at this era,he knew everything that they needed to be successful,and he did it in his first season,and it was that season he won the Lalliga,the other season,his attention was focused on the Champions league,he thought he would be able to lift that trophy,but it was so unfortunate for him and the team,they were removed in the quater finals of the tournament.
To me he tried,it isn't easy to build a team from it worst moment to a moment of joy when they lifted the Lalliga trophy,and I hope he finds a job at somewhere he would love.
Yes he did tried alot as he didn't meet his expectation, I know he still wish in his heart to stay and fight more for the clubs success but I think Laporta made or gave somethings which he might dislike or probably Laporta just freed him.... not to sure why he changed his mind the second time.
Barcelona could have achieved more IMV if Xavi had stayed more in the club because I think he has some plans for the team ,let's see the next move from the new coach hopefully he carries on right from where xavi stopped.
