Jamie Redknapp slammed Manchester United star Aaron Wan-Bissaka for what he did during the Red Devils' Premier League loss against Arsenal.The Gunners managed to secure a come-from-behind 3-2 win against Erik ten Hag's team and avenged their only loss so far. Mikel Arteta's team were beaten by a scoreline of 3-1 when the two met at Old Trafford earlier this season.Wan-Bissaka started the away game for United. While the right-back made a few crucial defensive contributions, his performance on the ball was not very convincing. Redknapp pointed that out as he said at Sky Sports' broadcast (via Daily Star):"I struggle with this one, where you’ve got an outfield player giving it back to the goalkeeper. He passes it out to the right back, Wan-Bissaka - the ball’s not his friend anyway, he doesn’t want it in that situation."Marcus Rashford opened the scoring for Manchester United with a stunning strike from well outside the box in the 17th minute.

Manchester United legend Roy Keane slammed the defender for his lack of concentration.Keane said (via Mirror):"It’s just his lack of awareness. It’s as if he can’t believe someone’s coming around the back of him, because he can see him, he just dozes off. A silly lack of concentration, considering we praise him saying he’s a good defender. Of course he [Wan-Bissaka] sees him [Nketiah]. You have to be aware of him, that’s his job, this is big boy stuff, these are big moments, do your job, go and attack the ball."Mark Goldbridge@markgoldbridgeGutted....that's on Glazers, Arnold, Murtough and co for leaving us with no options in big games.
