Out of favour Petr Cech has been linked with a move away from Stamford Bridge after losing his first=choice position.
London rivals are thought to be keen to sign the veteran as a replacement for Szczesny.
Mourinho is said to be happy to let the ‘keeper go for £10m, and Cech would be happy to move.
Hazard has given his blessing to a possible move.
“Thibaut and Petr are both very good, and when you are on the bench of course you want to play” he said.
“He knows he has the quality to play at a good club, and of course if I’m a good player and I’m on the bench I want to leave – this is football”
