Manchester United will invoke options to extend the contracts of Juan Mata, Ander Herrera, Ashley Young and Daley Blind until the end of next season.

The quartet are out of contract next summer but United will move to secure the players’ immediate futures and bolster their transfer values by triggering clauses that extend their deals by a further 12 months.

It is understood that United have already invoked the 12-month option on Luke Shaw’s contract to June 2019, which will strengthen United’s hopes of recouping a bigger portion of the £28 million fee they paid Southampton for the out of favour left back in 2014 as the club seek to offload him next year. Fenerbahce are one of the clubs interested in taking Shaw on loan in January but the player is thought to be unenthused by the prospect of a move to Turkey.

United are likely to listen to offers for Shaw in January but will still demand a fee in excess of £20 million, which, coupled with his £130,000 a week wages, could put off any interested parties. Spurs, Arsenal, Chelsea, Everton and Manchester City are thought to be keeping a watching brief.

Talks over a new long-term contract for Herrera have dragged on for 12 months now and, with the Spain midfielder free to talk to foreign suitors in January, United are ready to activate the option to avert that scenario unless there is a breakthrough in negotiations very soon. Herrera, 28, is keen to stay at Old Trafford, even though he is behind Paul Pogba, Nemanja Matic and Marouane Fellaini in the midfield pecking order.
