Marouane Fellaini has reportedly opted against signing a new contract at Manchester United as he is holding out for an improved offer.

The midfielder is highly regarded by manager Jose Mourinho, but the club's policy for players over 30 is to table one-year rolling contracts.

According to the Daily Mail, Fellaini's representatives feel that the Belgian international is worthy of a new long-term deal at Old Trafford.

Fellaini has started just one game so far this season, which was Sunday's 4-0 win over his former club Everton on home soil.

The midfielder, who is free to speak to clubs regarding a transfer in January as his current deal expires at the end of the season, has scored twice in four outings in all competitions in the current campaign.
