Interestingly, second league team players in England were surprised to see Ronaldo training with them

Portuguese attacker, 37, is desperate to leave Manchester United this summer and play football at the League Champions.

Ronaldo has yet to be held in his contract with Old Tuffford, but has not yet returned to pre-sezonal exercises with the Red Days.

But five times the Golden Ball winner discovered last week that he is still in good shape by sharing a picture of his physics on social networks.

And it's not just the gym the assailant used to preserve his physical condition.

He was seen in training with the team from Championship, Sheffield United.

The vetran has found that his interest in him is not as high as he predicted with a number of clubs that expelled himself from the race for his signature.

Both Chelsea and Bayern Munich have claimed they are not interested, while the star itself has zero interest in receiving a lucrative offer from an unidentified club from Saudi Arabia.

However, a new report from Spain today claims Ronaldo, who spent nine years at Real Madrid, has convinced Atletico chief Diego Simeone to sign it.
