Roy Keane cuttingly reminded Gary Neville that Sir Alex Ferguson made "mistakes" at Manchester United during a fractious live debate about their former club.
The pair of Red Devils legend were discussing the long-running issues at Old Trafford since Ferguson retired in 2013, with the in-studio discussion coming after United beat Tottenham Hotspur 3-2 on Saturday thanks to Cristiano Ronaldo 's triumphant hat-trick.
And it was hero Ronaldo that sparked the debate, as United interim boss Ralf Rangnick admitted post-match that managing the superstar was "challenging," having notably been back home in Portugal nursing an injury instead of being involved in the 4-1 humiliation at the hands of bitter rivals Manchester City last Sunday.
