Yeah, I agree with this. Ultimately though whether we do have an issue against teams that play 352 etc, we should still have enough for them. If they play Ronaldo and Cavani, then I don't think they can play at a great speed on the break.
For us in a game like this it's vital we don't give the ball away. I'd be tempted to let Kev sit this out and play Gundo and Bernardo to control the middle.
United are very vulnerable to pace, I'd be tempted to play Jesus on the right to threaten the channels behind Maguire.
