First off, I think Rafa has to go. I was rather neutral or even positive that we should keep Rafa till summer but yesterday's game proved me wrong. At the same time I think some people overhype Di Matteo. Champions League wasn't only because of his tactics and so on. It was also old-guard putting in good games and more-over LUCK. Di Matteo inserted self confidence and had instant positive impact on the players because of the negative relationships with AVB, who was sacked. Di Matteo did tire out our players, although he did make us play attacking football and it was very effective in the start of the season but it was fading as time wore on. There was no rotation what so ever and in the end of the day even athletes get tired and performance drops. Keep in mind he, too, lost two trophies and is responsible for failure in Champions League this season. Di Matteo is a great person, a gentleman but in no way a world class manager, not yet.
