Keane criticised Maddison for his lack of consistency earlier in the season, with the Tottenham star hitting back by scoring the winner against United in the Premier League clash between the two in February and doing his darts celebration. Keane then hit back by saying: "Good on him. Absolutely no problem. I still go with what I said, I don't think he does enough of that."
Maddison continued the light-hearted feud on Wednesday, saying: "I wasn't going to do any interviews but then I heard it was Roy Keane. Roy Keane, that's for you son."
