As Jose Mourinho paid respect to Arsene Wenger after his imminent Arsenal exit was announced, it seemed to confirm a recent shift in the relationship between the managers.
The Manchester United boss spoke of his "respect" for his Gunners counterpart when asked for his reaction to the news the Frenchman's reign in north London will come to an end at the end of the season.
At first, it sounded like a rare moment of diplomacy from Mourinho as one of his favourite verbal sparring partners bows out of the Premier League. However, having heard Wenger admit his "support" for the Portuguese and parise his team earlier this season, it could be that the animosity that has separated them over the years has died down.
United host Arsenal in the Premier League on Sunday in a game that will see the legendary managers go head-to-head on the field for the last time.
