The Times say West Ham would have to pay £15m in compensation to Manuel Pellegrini were they to sack him.
The newspaper say the club did not insert a termination clause in Pellegrini’s contract when they recruited him from Hebei China Fortune in the summer.
That would mean Pellegrini, who has made a dismal start as Hammers manager, would have his contract paid up in full unless both parties agree a severance package were he to be fired.
Meanwhile, Arsenal are being linked with former Chelsea left-back Filipe Luis.
He was tipped to join Paris St-Germain from Atletico Madrid during the recent transfer window but the move did not materialise.
And the Mirror have picked up on reports claiming that he could join Arsenal when the transfer window reopens in January.
The story originates from the website kickoff.co.uk, which claimed that he could move to the Emirates Stadium.
The Mirror have also picked up on reports that Arsenal are among clubs interested in Lille’s Ivory Coast winger Nicolas Pepe.
The Times say Arsenal boss Unai Emery and other members of the club’s management team are unhappy about the uncertainty surrounding the future of chief executive Ivan Gazidis.
Gazidis is reportedly considering an offer to leave the club and take a role at AC Milan.
