I think Xavi will be successful if he comes to Chelsea. He has a similar structure to Spanish coaches who are tactically good, such as Pep and Xabi. I think Xavi can choose Chelsea, which can buy him the players he wants. Xavi has a great game intelligence. He knows very well where to intervene in the game. Last year, despite the impossible odds, they finished ahead of Real Madrid and became champions. They closed this season with the second best finish. I think Xavi can be successful at Chelsea
Xavi that almost cried because Barcelona executives and fans weren't appreciating his work while managing Barcelona is what you guys are asking to come and manage Chelsea, with desperation of fans and board of directors asking for too much, if someone like Xavi should come to Chelsea and nothing changes, they will frustrate him and Todd Boehly will be incline to sell the hel remaining part of the club.
Xabi deserves better than Bayern Leverkusen right now but I'm not sure if a single season upgrade in performance is enough to move to another club, it will better if he improves his portfolio in Leverkusen, if there is sudden change in Manchester city taste of Guardiola style of game, Real Madrid will come for him and that's when I think it's perfect for him to increase his bid between this clubs and other interested clubs by that time.
