I see. All you want to prove is that Kounde is not poor in the air, well I don't remember any headers, but we created a lot of opportunities. I had a look at the stats, and we had 20 shots with 7 on target. So your theory may well be right, that he is decent in the air, but we created a lot of chances in that game with him in the Seville team.
As I said, if United buy a CB, then I hope they make the right choice, we only see the odd live match, or highlights on YouTube, so none of us are really in the best position to judge, the scouts and their reports should give the club the best insight. We all have our own opinions, that's why we are on this forum.
