Ander Herrera is frustrated over the way he has been treated by Manchester United.

The Daily Express says the midfielder is upset seeing so many of his teammates secured to new deals as his contract runs down.

The 29-year-old's performances have not gone unnoticed by the likes of Arsenal and PSG.

Herrera is said to have been offered a new deal worth £170,000-a-week including bonuses.

And on his future at the club the Spaniard was coy on what decision he would make.

He said: “I'm not going crazy about what is going to happen over the next four months because I don't know if my stay here is over."
