Roy Keane gives the most Roy Keane response after Gary Neville claims signing Man Utd shirt would 'devalue it'

Roy Keane accused Gary Neville of being "humble again" after the former Manchester United defender claimed he would "devalue" a shirt after signing it.

Neville has often played down his ability as a player, despite being regarded by many as one of the Premier League's greatest ever full-backs. In fact, he memorably left himself out when picking an all-time Manchester United eleven.

Having made more than 600 appearances under Sir Alex Ferguson across an impressive 19-year career, the 49-year-old should, in my opinion, give himself more credit.

Still, the Sky Sports pundit continues to downplay his career in football. In fact, while appearing on the latest episode of The Overlap – brought to you by Sky Bet – he was at it again.

As you can see in the footage above, Neville was sitting alongside former Manchester United teammates Roy Keane and Wayne Rooney when a member of the crew asked for them to sign a number of shirts.

Keane and Rooney can be seen penning their autographs onto the jersey but Neville, who is sat away from the duo, makes his feelings clear.

"Do you know something," he said. "If you've got Rooney and Keane on a United shirt, do I actually devalue it? There comes a point when you devalue it a little bit."

Keane, far from impressed by Neville's comment, responds: "Oh you're being humble again!"

In his early years at Old Trafford, Neville "felt like he didn’t belong" in the team and was "overwhelmed" to share a dressing room with the likes of Keane and Bryan Robson.

"Honestly, I used to go in there and get changed, there was me, Scholes, and Butty – Becks was delayed as he was a year later than us and Giggsy was already there – I remember that I used to walk back into my own dressing room after I’d got changed," he said on the Stick To Football podcast.

"It was massively overwhelming, in terms of the presence of the people in the dressing room. Mark Hughes was my hero; Bryan Robson was still at the club when I made my Premier League debut. I’ve got goosebumps of me being in there and it scares me to death."

He added: "In the youth team and reserves, I was the captain, so I’d get changed and go back into the youth team dressing room. [David] Beckham would be in there, Phil [Neville] would be in there – I felt like I didn’t belong [in the first team dressing room]."
