For me Winks is a number 8. He's the link/pivot between the holding midfielder and the attacking midfielders. If we play 2 in the middle he's the one in the Dembele role just ahead of Dier/Wanyama. If we play a 3 he's one of 2 number 8s with one other either side of the holder. In a positional sense he's Dembele, he wont be the last line of defensive midfield and he wont create/score many goals, but he'll orchestrate the midfield.
But here in is part of our problem of the last 3 to 4 years. I think every great team needs a goal scoring/assisting midfielder. It’s obviously a tactical decision but for me the more advanced midfielder needs to offer more than just being a link in a 2. Much like Gerrard Lampard and scholes. They were all that link player but obviously contributed a lot more. We’ve basically had dembele in that role. And yes obviously I understand his role but as said to be a great team I think that player has to offer more. Which is why personally I would have winks as the deeper of a 2. And if your talking about a 3 then the the 2 wider players definitely need to offer more as in de bruyne and silva.
