Ander Herrera will be offered a new £120,000-a-week contract at Old Trafford this summer after emerging as one of Manchester United’s most important players under Jose Mourinho.

Herrera had arguably his best game for United in Sunday’s win over Chelsea as he set up the first goal, scored the second and did a superb man-marking job on Eden Hazard.

The 27-year-old Spain midfielder has become a key figure since Mourinho arrived in the summer even though he was understood to have reservations about how he would fit in under the Portuguese coach.

United are keen to reward Herrera with a new contract and plan to open talks with the player and his representatives before the start of next season.

Herrera has just over a year left on the deal he agreed after signing from Athletic Bilbao for £29million in the summer of 2014, although United have an option to extend it by another 12 months.

The club do not expect any problems in negotiating new terms with the player’s camp, and Herrera said in February that he would be happy to begin contract talks.
