A tennis fan has gone viral after giving a hilarious reaction to Feliciano Lopez changing his shirt during the US Open.The moment was captured when Lopez changed his jersey during his four-set first round victory over American Taylor Fritz at Flushing Meadow.One eagle-eyed fan was quick to notice a shirtless Lopez and reached for her phone to ensure that she captured the moment before any other spectator had spotted the opportunity.The fan was visibly pleased with herself for taking the photo and smiled contently as Lopez put on a fresh jersey to resume the match.The 37-year-old had lost the first set 6-3, but went on to win the match and progress to the next stage of the competition, where he will face Yoshihito Nishioka in the second round.

The result, however, has been overshadowed by the cheeky reaction of one fan to the shirtless Spaniard. 

Several other fans have since taken to Twitter to comment on how relatable the woman's reaction was. Unfortunately for these admirers, Lopez is currently in a relationship with model Sandra Gago.

The presence of a fiancee, however, is unlikely to stop tennis fans around the world from admiring the sportsman's physique.

The fan's reaction to the topless athlete is hardly surprising given the tennis player's modelling career away from the court.

The veteran tennis player has modelled for Hugo Boss and Elle, but has stated that he does not want to be seen as a model, but rather as a tennis player.

Whilst casual tennis fans may not be aware of Lopez, he currently holds the record for appearing at the most consecutive Grand Slams, with his tally standing at an astonishing 70.

The Spaniard has also reached the final of the doubles at two Grand Slams, winning the French Open with compatriot Marc Lopez.
