Manchester United midfielder Ander Herrera calls out team-mate David de Gea as he pulls off stunning save on beach pitch while on holiday

Manchester United boss Jose Mourinho is growing frustrated at the lack of action in the transfer market, but it looks as though he has nothing to worry about in the goalkeeping department. 

They already have one of the world's finest in the form of David de Gea, but it would appear there is a man in the United ranks ready to dethrone the No 1, with Ander Herrera showing off his abilities between the sticks on holiday.

Against a fake tropical island backdrop, the midfielder swapped outfield for goal, as he lined up on a beach pitch to face down a penalty kick while on holiday, and the transition was seamless.

Herrera dived at full length to his left to tip a shot round the post with cat-like reflexes. 

Proud of the save, the Spain international posted it to his Instagram account, along with a message for the incumbent United No 1, and his fellow Old Trafford shot-stoppers.

'Hi David De Gea, Chiqui (Sergio Romero) and Joel Pereira , I hope you guys are enjoying your holidays but you should be a bit scared,' said Herrera's menacing post.

While United have struggled for incomings this summer - completing only the signing of central defender Victor Lindelof to date - Herrera was linked with a move away from the club last month.

However, the 27-year-old played down all speculation linking him with a move back to Spain to join Barcelona, and insisted that he is raring to go for another season under Jose Mourinho.
