Manchester United legend Paul Scholes believes Ander Herrera has been Manchester United's most impressive signing under Louis van Gaal.

Herrera arrived at Old Trafford in a £28m deal from Athletic Bilbao, signing a four-year contract last summer, and after a slow start has come into his own at Old Trafford.

Speaking on Newstalk 106-108 FM Scholes said: "I think it was difficult for all the signings at first.

"The first six, seven, eight months were very difficult.

"I think I'd have to say Herrera's the one who's impressed me most.

"He was another one who did struggle.

"He struggled to get in the team at first, but he's playing really well, playing really good football, looks like he's going to score goals and looks like he's going to make goals.

"He's been a really good addition.

"He's only young as well so hopeful he can get even better."

Herrera has scored 7seven goals and provided five assists in 27 appearances for the Red Devils in his debut season.
