Speaking exclusively with Crypto Casino LTD, the Man Utd legend said: "If Jeremie Frimpong is a bit fragile defensively, then he'll be bought for a certain system by the manager. Nowadays, fullbacks play much higher up the pitch and can play in all types of systems, but I don't know how Erik ten Hag wants to play. Man United already have a good right back in Aaron Wan-Bissaka, but you can say he's the opposite of Frimpong, great defensively but not that great going forward.
“When we attack, we should be letting Wan Bissaka sit back and offer more defensive protection, handling the one v one on the wing. But instead, he's told to bomb up the wing and try to take on a player, which he can't do. Erik ten Hag should take away Wan-Bissaka's attacking duties and make him defend, then they can have some solidarity in the defence. Instead, Wan-Bissaka, who doesn't score or create, run around like a headless chicken in the opposition box, running in his teammates' way.
“It's not rocket science, watching this unfold is crazy. The one thing you need in the defence is to be able to defend one v one. Just let him f***ing defend."
