Michail Antonio has signed a new four-year contract at West Ham following protracted talks with the Hammers' player of the season.
Antonio, who signed a new deal until 2020 less than a year ago, has added a further year until 2021 and joked "it's about time", having discussed a new contract since January.
Sky sources reported in early April that talks were at a standstill, with the player not satisfied with the terms offered to him by the east London club - but he is now understood to be earning around £70,000 per week.
But the player had been keen to stay and, following a Hammers' source telling Sky Sports News HQ that Antonio was "going nowhere" this summer, the club have finally made a breakthrough.
Antonio, who is out for the rest of the season with a hamstring problem, said: "I'm over the moon, I've loved my time here and I'm just happy that we have managed to get things sorted so I can move onto next season and do what I've done this season.
"I'd like to thank the chairman [David Sullivan] because we had a nice little deal for this to get sorted. He's a lovely man and thanks very much."
Sullivan said: "His best years are still ahead of him and we are looking forward to seeing him spend them in a Claret and Blue shirt. We wish Michail well with the rehabilitation off his hamstring injury and look forward to seeing him come back stronger next season."
Antonio joined West Ham from Nottingham Forest in a £7m deal in 2015.
