Manchester United may have to wait until January to re-sign David De Gea.

The Spaniard has agreed to a £350,000-a-week deal in principle.

However, there is a new contract clause being introduced by the club which has irked De Gea and other United players.

A 25 per cent pay cut will be kick in should United fail to finish in the top-four this season, according to The Sun.

PSG are monitoring the situation in case the situation remains unresolved in January.

De Gea will be able to sign a pre-contract agreement with foreign clubs in the new year.
