Twitter users believe that Tom Brady decided to come out of retirement after speaking to Cristiano Ronaldo following Manchester United's win over Tottenham on Saturday.
The NFL icon confirmed on Sunday that he would be re-joining the Tampa Bay Buccaneers, just six weeks after announcing he was quitting the sport.
It is a stunning career U-turn from Brady, 44, who has won a record seven Super Bowl crowns across 22 glittering seasons.
