We had players in the box against Spurs 1st half but zero quality in and around it.
I agree - but we pushed Spurs back.
In fact, barring 2 minutes where our entire defence fell asleep and they scored, we restricted them to very little in the first half and that's because we actually offered a semblance of a threat up top.
What we lacked there was pace getting up in support of Tosun quickly - we had Bolasie wide and then Rooney and Gylfi trying to 'bomb on'. Now throw in Walcott to that and suddenly you have a very quick player who can get us up the pitch in central areas.
I've said it before with Lookman. Players like that should be played centrally - look at the impact it had with Gray and Mahrez at Leicester.
You can't deal with pace down the middle. And neither Lookman or Walcott are classic wingers in the sense that they want to get to the byline and cross.
So play them centrally - as the link man between defence and attack.
Another great example of that this season is Lingard. Slightly different in the sense he probably works harder defensively, but in terms of playing style he's a very quick, nimble player who provides that 'transition' player for United.
