After Jurgen Klopp's spat with pundits Phil and Gary Neville it seemed inevitable that other managers would follow suit. Manchester United boss Jose Mourinho has wasted little time in taking a mischievous swipe at BT Sport analyst Michael Owen, after he had the temerity to question Zlatan Ibrahimovic's value to his side.

When the comments were replayed to Owen, he remarked: "Managers are getting awfully touchy, aren't they?"
He also hit back by insisting his goals for United were worth more "because I cost about ten per cent of what Zlatan is on a week".

United fans may be relieved to see Mourinho speaking with a twinkle in his eye once again. For much of his time at Old Trafford, the Portuguese manager has cut a morose figure, short with the press and his players alike. Over at Anfield, the avuncular Klopp has been his usual charming self.
But the two incidents this week suggest the roles could be reversing in line with performances on the pitch. United beat Spurs on Sunday and are now unbeaten in the league since October. Liverpool followed up their shock defeat to Bournemouth with a draw against struggling West Ham at Anfield at the weekend.
