The Debate: What Onana brings to United

"But it's just progression of what the manager knows about and wants," our former full-back continued.

"You've mentioned [Lisandro] Martinez and Antony, and obviously [Tyrell] Malacia; he's plucked him [Onana] from the same league [the Eredivisie] as he was manager in, he's done particularly well and I thought we made great strides last year from where we were the season before.

"Hopefully we can do that again this season."

Fellow United legend Andy Cole believes that Onana's footwork will make him a key asset for Erik ten Hag's side, but maintains that this mustn't detract from his ability to keep the ball out of the net.

"For me, a goalkeeper should keep the ball out of the back of the net, but if you look at him last season, I've watched the Champions League final, he looked really good with his feet too.

"Obviously he's very good as a goalkeeper. So fingers crossed he works out just like Erik's other signings.

"Martinez has worked extremely well for him. I think he's been fantastic."
