I know people are worried about our defence, but I don't think this is enough justification to start Tévez over Berbatov. We'll still have a decent backline and goalkeeper, and we'll (most likely) have hard workers in the midfield such as Park, Fletcher, Giggs, or Carrick (or even Scholes) depending on who is chosen, as well as Rooney up top.
I think the key to Berbatov is that he will hold the ball up, which is less likely from any of our other players. If we can hold the ball up, we're more likely to get players forward in time to cause Inter problems.
I think we can nick it tonight in all honesty, so I'll say:
Inter Milan 1-2 Manchester United
But all in all, I think if we score in Italy, we'll win the tie overall anyway (That's what I said for both games against Roma, so hopefully it'll work again tonight lol).
