Come off it man. Look at the Juve v Madrid, and Bayern v Barca games.
He'd be so out of place it's unreal. We used to be a top 4/6 side in Europe under Ferguson, and now we are so far behind its unreal. That's the level we should be aiming to be at.
Ironically enough, I think Bayern could have done with a good outball like Fellaini tonight. Barca's high press pinned them back and they were forced to punt the ball upfield time and time again, instantly forfeiting possession.
You can talk about Bayern but they lost 3-0 and it should have been more, given how many chances Barca fluffed in the opening 15 minutes.
As I said, Fellaini is very much a big game player, and not every single player can be a Lionel Messi. Even the mighty Barcelona have seen the need to invest in a little bit of physicality with the likes of Rakitic and Suarez, and they are one of the greatest club sides of all time with one of the best individual players of all time. We can aim at that level all we like, but you and others need to face the fact that it simply may not happen - we had the class of '92, Barca had the class of.... '05 or whenever it was. Would I like for the footballing gods to bless us with another team like that? Sure, but in the meantime it is a ridiculous attitude to think we can simply buy that level of success over the course of a muppet summer or two.
As others have stated, very few of our players would make the Barca first eleven, and personally I think that sort of side is primarily the product of years of careful development - which our current team has not had - than simply trying to fill the team with superstars (see Di Maria and Falcao).
Pep may not want to have a Fellaini in his team, but I bet Mourinho would.
