I don't know about 'better' but we're certainly more patient, 6 years... Let me repeat that SIX YEARS!! without a single challenge.. RM fans would have car bombed some-one by now im sure ..My friend, all players who have joined Real Madrid have not regretted it.
Top players like Ronaldo, Bale, Owen, etc, all wanted to stay in Madrid, for as long as they could. And this was after the abuse suffered at the hands of the demanding RMFC supporters.
To say that MUFC has better fans and that is why players should choose MUFC is ridiculous (assuming that is what you are implying).
Also like @Pogue Mahone has stated that's not even what I'm suggesting.. I'm not saying Pogba will regret going to RM, but if he's upset over that one MU fan screaming at him, then he's gonna have the shock of his life with RM fans..
