I started watching Watford more and more to understand how they are making this work, and came to the conclusion that it is not really a true old school 4-4-2 that Watford employ, the midfield is quite narrow and the width comes from the full backs.
Deeney is basically a new Heskey - this is meant to be a complement, but he's rarely playing up against the opposite CB's, always drops into the whole to flick things on for Ighalo running behind.
Consider it a compliment that Pochettino actually changed his system to a 3-4-2-1 Dier as a sweeper to counteract Ighalo and Deeney, obviously he didn't fancy our cultured Belgian CB's up against them in a individual physical battle.
The ref made a rod for his own back with the Alli on Capouè tackle, got the ball but follow through cased a reaction.
There can be no arguments with Ake's red.
just a shame we can't get him and Eriksen playing well at the same time.
