As Ten Hag joined the ITV crew, Keane told the head coach: "You must be proud of them, we've always questioned players about their quality at Man United, but character and leadership. They showed character today - which I had questioned, and a lot of people have...you shouldn't listen to them pundits anyway! Take no notice of the pundits.
The Dutchman then responded by saying: "But you told me!" before Keane pointed at fellow pundits Ian Wright and Joleon Lescott and said: "No, them two!"
The United boss then took a dig at Keane's managerial career as he said: "You had trouble to manage a team!"
This led to Keane saying: "Ah, I won a Championship with Sunderland...give me some praise, ah come on! You're too harsh on me!"
The manager then tried to explain his statement by saying: "What I said to you," before the pundit interrupted by saying: "I agree."
