4-4-Grealish-1 ...... Yes I play football manager .
It would make us defensively better and play Jack where he should be played. We couldn't be any more impotent in attack than we are now, so that would probably improve too.
Get rid of wingers, play Elmo on the right and CH on the left, chuck in Luiz and McGinn. Stack that midfield, release Jack and let him do his thing.
Tongue in cheek, yes ..... Pretty sure it would work though....
