Xabi Alonso is one good coach but he shouldn’t be compared to Pep and Mourinho yet, though he wouldn’t want to come as he’s Madrid bound. I think Chelsea should watch out for Xavi or probably get Mourinho a return back to the club. The results keep getting crazy and the fans are actually tired of this. Crazy how the pride of London are now the Laughing stock of the city.
Sorry but I really believe in Xabi's abilities as a coach. Even though Xabi cannot be compared to Pep or Mourinho because they are older and more experienced, a young coach can also be a great coach nowadays because of his openness of information and ability to adapt to the times. What this means is that modern football is not the same as football in the past, so every coach, be it Pep or Xabi, has the same opportunity to become a great coach.
I don’t think anyone will doubt Xavi after what he did in the Bundesliga. He is still undefeated in the Bundesliga and the only team to stay undefeated in Europe's top leagues. It is a record breaker in the Bundesliga. But here is the thing, I don't think he is ready yet to manage big teams with high expectations such as Chelsea and Manchester United. The expectations are bigger there and the fans are really crazy as well. He needs a few more years with mid tier teams before he can join big teams.
Chelsea and Manchester United both need a change in coaching staff but I don't Xabi is the right fit for both of them.
