Herrera has struggled for consistent starts at Manchester United this season with £40m summer signing Matic getting the nod from Jose Mourinho.

The Serbian has been superb since his switch from Chelsea, helping United to sit joint top of the Premier League table.

Herrera has hailed his new team as one of the best in the world but the Spaniard insists he’ll be ready whenever Mourinho calls upon him.

The 28-year-old said: "There will be a lot of games this season, so we will sometimes play with two and sometimes with three, so we have a lot of solutions.

"Matic is a master, one of the best in the world in that position, and I think he is going to help us a lot. With [Michael] Carrick and Matic I have two mentors that I can learn from.

"I know I can play more forward than them, when we play with three, so I will be there for the manager whenever he needs me. Sometimes as number six, sometimes as number eight, sometimes No. 10."

Herrera has also heaped praise on United’s currently crocked superstar Paul Pogba.

He added: “I feel very good to play with Paul.

"We know his qualities. His football is free, so you can't keep him in one position, because then you lose all his qualities. So, when you play with him, you know he can win the game for you.

"I think there are not too many midfielders who can score 10 goals and give 12 assists, so we have to give him the freedom he deserves to win games for us.

"Matic, Carrick, Fellaini and myself have to help him be the best in the world. If we are there to balance the midfield, he can score goals for you and give assists. He is a fantastic player."

United take on Crystal Palace in their Premier League clash at Old Trafford tomorrow.
