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.
De Gea and Ronaldo's were team-mates during the former's during the latter's second spell at Old Trafford.
IT'S ON! 💥 @erakulis_app is a project very close to my heart. Born from my desire to promote a balanced and healthy lifestyle for everyone. Now, the tools to care for your body and mind are right at your fingertips!

Both men have since left Man United in acrimonious circumstances.
Ronaldo fell out of favour under manager Erik ten Hag and orchestrated his own exit through a bombshell interview.
The Portuguese joined Al-Nassr, becoming the most highly paid player in world football.
De Gea, meanwhile, still finds himself without a club after his United contract was allowed to expire following a breakdown in negotiations in the summer.
