Sam Allardyce is reportedly ready to spend upwards of £50 million to secure a double deal for both Mawson and Watford’s Abdoulaye Doucoure.
West Ham have been heavily linked with a move for Mawson and have reportedly had a bid turned down.
With ageing central defenders in the former of Ashley Williams and Phil Jagielka, Allardyce is keen to sign another central defender.
Doucoure, who has impressed for Watford under Marco Silva, has been identified as a cheaper alternative to Steven N’Zonzi, who has been linked with a move to Goodison Park ever since Allardyce took the job.
Allardyce has turned Everton’s season around after some early relegation fears but wants to ensure a strong finish.
