De Gea to PSG and Neymar to Real Madrid?

David de Gea could become one of next summer's bargain signings as his contract is set to run out in June, meaning he will be available on a free transfer if Manchester United cannot extend his deal. The Spaniard's future appears to be away from the 'Red Devils'.
The English club have the possibility to activate a unilateral contract renewal, though it is said that De Gea has already decided to leave Old Trafford.
According to the 'Daily Mail', the goalkeeper's next destination will be PSG, who will make him the world's highest-paid goalkeeper with a salary of 17.6 million euros per season. The proposed contract would last for four years, meaning De Gea would earn more than 70 million euros in France.
It is also reported that if this deal is to happen, in order to comply with Financial Fair Play, PSG intend to sell Neymar to Real Madrid.
Should United decide to unilaterally extend De Gea's contract until June 2020, the goalkeeper would arrive in Paris on a free transfer and the Brazilian's transfer to Real Madrid would take place the following summer.
The 'Daily Mail' also claim that signing a 'top' goalkeeper is Thomas Tuchel's main priority once Buffon leaves at the end of the season, after noticing the gulf in quality between PSG's attack and defence.
