Manchester United legend Roy Keane has taken a cheeky jibe at former Arsenal nemesis Patrick Vieira.
The pair clashed multiple times, sometimes off the pitch, during the United-Gunners rivalry of the early 2000's.
Keane was full of praise when reflecting on Vieira's ability, but added that the Frenchman would've been a bench player had he joined United.
He told Sky Sports: "There was talk about Patrick [going to United], but I don't think he would have got into the United team. He would've had to have been a squad player and I don't think he would've been satisfied with that.
"What we would've done, when Veron came to the club, you see that as a challenge. The club has to improve, get better and you have to roll with it, roll your sleeves up and enjoy the challenge. If you want to be a big player at a big club, you have to accept these challenges.
He continued: "It was a big challenge for me when Patrick came onto the scene.
"He was a good player and I knew I had to be at my best when I was up against him. He was nasty, he could put his foot in and he could score a goal.
"Patrick would've been my toughest opponent at the time. He would challenge you in different ways. He would get around the pitch, he was good with the ball, he was strong, and he had a goal in him. I knew I had to be at my very, very best to get on top of Patrick.
"There was a respect towards Patrick. It was the same with the lads coming through. I go back to Steven Gerrard and the Frank Lampard. You had to be at your best. I had huge respect for him, but I knew if I could win my battle it would give us a better chance of winning the game."
