Michail Antonio's talks over a new West Ham contract are at a standstill after he rejected their first offer, according to Sky sources.
It is understood the 27-year-old is frustrated that he has not been offered parity with the club's other top stars having established himself as a key player for Slaven Bilic.
Sky Sports News HQ has been told that Antonio feels he is being penalised for having come from a Championship club, having signed from Nottingham Forest in 2015.
And he is hoping the club rewards the fact he has been willing to play in defence, midfield and up-front for the team, and came off his sick bed to play with flu back in January.
It is understood that renewed talks will not take place for the foreseeable future but Antonio is happy at the Hammers and is keen to stay - and Bilic says the club will offer him fresh terms in the summer.
Ahead of their trip to Arsenal on Wednesday, Bilic said: "The club and chairman appreciate the job and work he has done for us.
"The club is offering him a new contract definitely this summer. He is keen to stay, yes, and has a long contract here. It's not like he has one year left and the club has to panic, no.
"We appreciate what he has done and we want to make him happy and keep him for a long time, and secure him, and the club is preparing that."
Antonio signed a new deal until 2020 in July 2016.
