Paul Pogba appeared to post a sarcastic response to Pep Guardiola's claim that the Manchester United midfielder was offered to City two months ago.
Guardiola, who was labeled a 'dog' and a 'coward' by Pogba's agent Mino Raiola over his management of Zlatan Ibrahimovic at Barcelona eight years ago, alleged that Raiola offered Pogba and Henrikh Mkhitaryan to the champions-elect earlier this year.
Pogba is less than two years into a five-year United contract with the option of an additional year and it is unthinkable that United would allow him to join their neighbors.
After the embargo for Guardiola's comments was broken by an irresponsible Italian journalist on Friday afternoon, Pogba posted a photo from United's Friday training session under an hour later.
The picture of Pogba, holding his hand to ear, was accompanied by the caption: 'Say what' and an ear emoji. Raiola is also on Twitter but has not tweeted at the time of writing.
Guardiola said: "Two months ago he (Raiola) offered me Mkhitaryan and Pogba to play with us. Why did he offer? Was he interested in Mhikitarian and Pogba playing with us?
"So he has to protect his players and he cannot bring the players to a guy like me, like a dog. I said no. We don’t have enough money to buy Pogba because he is so expensive."
