David de Gea couldn't resist poking fun at Cristiano Ronaldo after his former team-mate announced his latest brand deal on Wednesday.
Ronaldo took to Twitter to announce the launch of his new health and wellness app Erakulis.
The app promises to offer help with mental health, nutrition and fitness, as well as online appointments with experts.
However, De Gea decided to have a bit of fun in response, sharing a GIF of himself and Paul Pogba in which he asks 'who?' and adding a pair of laughing emojis.
