David de Gea will be staying with Manchester United next season - no matter what.

The Sun says United will use their option to extend De Gea's contract six months early — if he fails to agree a new deal by January.

But it would leave Europe's biggest hitters believing they could get the Spain No 1 in the summer.

De Gea has been offered a five-year, £375,000-a-week deal, including various clean sheet add-ons, which would put only Alexis Sanchez ahead in Old Trafford pay stakes.

Yet De Gea has still not signed — and United have set an end-of-year deadline after finally running out of patience.

If he continues to delay, the likes of Barcelona and Paris Saint-Germain will think they can grab him at the end of the season.

United were expected to take up a 12-month extension when his deal expires in the summer.
