Nemanja Matic had no issue with poking the ego of Cristiano Ronaldo this week, after taunting Manchester United's talisman for losing in training.
Followers of Ronaldo on social media will have noticed his regular image posts from United's Carrington base, showing himself with team-mates often along with the caption 'winning team.'
So, when Matic guided a side to victory over Ronaldo this week the Serbian star certainly made a point of letting him know.
Uploading a squad photo, Matic and his fellow stars could be seen punching the air or holding arms aloft in celebration.
Captioning the image, which he published for his two million followers to see, Matic added: 'Winning team! @Cristiano are you ok?' along with a laughing face.
