Manchester United midfielder Ander Herrera has claimed that his future at Old Trafford will never be fully secure, but says he is happy and eager to fight for his place at the "biggest club in England."

The Red Devils have won their last three Premier League fixtures and are unbeaten in six, with Herrera completing the full 90 minutes on each occasion.

Asked whether he plans to remain with the club, the 27-year-old told Inside United: "Yes, but you never know because if I want to keep playing for United you have to play very well because United is the biggest club in England.

"The club has the capacity to bring any players here so you have to always be at your highest level if you want to keep playing for this club. It's not easy but I hope I can and I will fight for it."

Herrera joined United in 2014 from Spanish side Athletic Bilbao.
