I don't think Utd would have looked stupid even if that had have happened, just as we won't if Dwamena is ok. The medical advice (on both occasions) was that there was a risk, and that's enough to not spend a fortune.Remember when Man Utd pulled out of the deal to sign Ruud Van Nistelrooy? PSV were in complete disagreement about the knee injury Man Utd had detected, so they filmed and broadcast his next training session with them. His knee erupts and he's lying on the ground screaming. It could have gone the other way, he could have banged in the goals and made United look stupid but their concern was still justified.
I'm not sure Dwamena will want to play in the Championship.Let's hope we go back for him when he is given the all clear/or fixed like Man Utd returned for Van Nistelrooy.
