Since we started playing 2 DMs recently, we drew at Chelsea and Sunderland and beat Swansea and Bolton, very good form, then went back to two wingers and lost at home to Norwich.
ATM we're better with two DMs than two wingers, and Lennon's stats point to the fact that he isn't part of our best XI.
I can see why Harry gambled v Norwich, but it failed, miserably and probably has done for our CL place.
I don't like two wingers in general, and certainly Lennon and Bale against Norwich far from giving us balance actually unbalanced us. Sandro with Livermore and Modric would have given us more balance.
I don't know what's our best formation, but as PS convincingly argues 4-4-1-1 (with two wingers) isn't the one that is the best AFAIC.
