Manchester United are becoming increasingly nervous about David De Gea's future.

Negotiations over a contract extension for the Spaniard have stalled.

De Gea's current deal expires in June, which means he will be able to leave on a free transfer.

According to The Telegraph, United have presented the 28-year-old with a new deal worth £275,000 a week.

However, De Gea has not yet responded to the offer and the United hierarchy is starting to worry.

PSG and Juventus are monitoring the situation at Old Trafford.
