Ander Herrera wants to repay Manchester United's faith in him
Ander Herrera has said he is keen to repay Manchester United's faith amid speculation that he is a summer target for Barcelona.
Midfielder Herrera has been linked with a return to Spain after his former Athletic Bilbao manager Ernesto Valverde took over from Luis Enrique at Barcelona.
But the 27-year-old, United's Player of the Year, has indicated that he wants to stay at Old Trafford.
"I'm very thankful with Man United because they came to Spain to sign me three years ago," he told Sky Sports.
"So the only thing I have in my mind every time I am on the pitch is I want to give all the affection back and I think that's the right way.
"I want to keep winning things, I am happy with my development, I am happy with my time at the club so far but I am not going to stop here.
"I want to keep playing, keep improving and making our fans proud."
Meanwhile, his fellow United midfielder Marouane Fellaini has left the door open for a future move to the Chinese Super League.
In January, Fellaini signed a one-year extension to keep him at Old Trafford until 2018 but said he was open to the possibility of playing in the Far East.
"Why not in the future?" he told VTM news. "I don't know. I can't say that now, I'm under contract with Manchester United for now. Why not?"
He praised United manager Jose Mourinho as "a great coach" and added: "He's here to win trophies, he's proven that, he's shown that.
"It's only his first year -- you have to let him work, and I'm sure he'll do very good work at Manchester United.
"He knows how to use me. At the start of the season, I started as a No. 6, then as a No. 8, I've played as a No. 10. I play further up the pitch when he needs me.
"He knows my qualities, he knows how to use me. When he calls on me, I give my all and try to contribute."
