Spanish goalkeeper David de Gea is reportedly becoming 'increasingly frustrated' with Manchester United's refusal to meet his wage demands.
The 28-year-old will see his contract with the Red Devils expire at the end of next season.
The two parties have been locked in talks for some time, but it is understood that the stopper's wage demands are proving problematic.
The Red Devils will reportedly refuse to sell De Gea this summer, but according to The Times, the Spain international 'is growing increasingly frustrated' with the current situation.
Real Madrid continue to be linked with a move in this summer's transfer window, while Paris Saint-Germain have also been credited with an interest.
Ander Herrera and Juan Mata, meanwhile, are also reportedly unhappy with the 20-time English champions due to their own contract situations.
