I think I'd definitely have Lucas sitting in front of the back four ,the Bitterz wont admit it but they do like the long ball . I'd also be tempted to play Brannagan alongside Allen as he has everything in his locker to make a top CM ,add to the fact he's tenacious and doesn't shirk a tackle and he's practically tailor made for our midfield.
The lad impressed when he played alongside Chirivella ,and against a well drilled ,combative and industrious West Ham team he never hid. One things for sure we need pace and speed of thought in that midfield and Milner given his lack of mobility doesn't provide that.
