I would suggest they won the league because they had very good football players.
They only started playing well with 5 at the back. The beginning of the season they weren't winning.
Not to say we should be playing it. Surely with 5 at the back we should have a rb and lb out wide to stop the cross coming in and then if it does have the CB to deal with it.
Our full backs are so narrow and the three cb have no idea where they should be.
Davies has been bad. Not good enough. Schneider Lin has been pretty good and Keane has played so great balls from he back. Bolasie looks lovely.
