Well we could all say they would have done this or that, but the bottom line is they haven't, yet both have played considerably more games in Europe than Bale has, and for a better team.
Utd have played both good teams in Europe and poor ones, Valencia and Nani have had good games and poor ones, but has any of them ever destroyed a team of that standard or even a lesser one, like Bale did to Inter? It is easy to say well Inter were shit and slow, but at the time they were CL winners and Maicon was considered to be one of the best RB's about after an excellent WC, yet Bale repeatedly destroyed him.
I would be interested to know if any of our wingers, Giggs and Ronaldo included, have ever single handedly destroyed a top team like Bale did. If they have i will be honest i am struggling to remember it. We have had some great team performances over the years but in terms of an individual performance like that, i am struggling to recall even one such performance.
