I think its more to do with team selection and tactics. Fellaini was clearly instructed to sit deep, as evident in the first half, and so on and so forth. Moyes better learn quick, we are not perennial underdogs like Everton.
Don't tell me you'll have Young in your team. Young out, anyone else in. Team not entirely set to counter attack. Simples.
Young clearly started to try and get an early penalty - that didn't work so subbed him as he's complete **** at football.
