Funny. I think the real wums are the one's saying that he isn't good enough for United. Not good enough for United but good enough for the team in second.
He "doesn't have much to his game" yet he is a great tackler and passer. Take a look at his through balls which he is excellent at and take a look at all the counter attacks he starts by making a tackle and then making a quick incisive pass, something that the United midfield struggles with; moving the ball quickly and making the pass quickly.
He isn't "technical enough for United" yet he's a product of Sporting's academy and his technical ability has always been one of his strong suits since arriving. He has an extremely accurate long ball. He has excellent ball control (take a look at his goal today) and he is also pretty good with dribbling in tight spaces and dribbling past players while keeping the ball under control and retaining posession. He has a very accurate free kick (take a look at his free kick goals).
Dier would be an upgrade on that United midfield and anyone who thinks otherwise is much more of a wum than I am.
You've all been complaining all season about needing a DM to "set Pogba free"
but a DM/CB of the team with the best defensive record in the league (and the best defensive record last season) isn't good enough?!
