He played a great ball which won us the penalty & red card in the first place. As a team we were struggling with an insanely good Southampton pressing game and I don't think he was notably struggling any more than others, and was actually dealing with it better than most.
And we didn't not beat Liverpool or Southampton because of Winks, in fact if our other midfielders had put in performances on the level he did, we win both.
But yes, we still need to be bringing in better midfielders, it's a weak area. But for now, with the players we actually have, Winks is justifying his place. That's all I really care about for now, Conte can't play midfielders we don't actually have yet.
