James Ward-Prowse has promised to give his all for West Ham United after completing his move from Southampton.

The 28-year-old has joined for an undisclosed fee, signing a deal until June 2027, and is the second summer signing for the club after the arrival of Mexican midfielder Edson Alvarez.

England international Ward-Prowse made 343 Premier League appearances for the Saints and could make his Hammers debut against Chelsea at London Stadium on Sunday.

"I'm buzzing to be here at West Ham United. It's great to be here and I'm looking forward to getting going," he told whufc.com.

“From the outside looking in, this is a club that has been on the rise for a number of years now and coming off the success in the UEFA Europa Conference League last year, you can feel there is real momentum around this club. 

"It’s great to be a part of it and I can’t wait to play my role in the games to come.

“When I think about my game, it is based on hard work, graft, and giving 100 per cent. West Ham United has always been a club that has epitomises that. 

"You can feel that from the fans and you can see it in the players who are here and the lads that have come through the Academy too.

“I feel as though I will fit straight in and I can promise I will give my all for this football club in my time here.”

West Ham boss David Moyes was delighted to get the experienced midfielder on board, given his reputation as one of the best set-piece takers in the top flight.

“I’m delighted to bring a player of James’ quality and experience to West Ham United,” said Moyes.

“He's performed to a very high level in the Premier League over the last decade, constantly producing good numbers season after season.

“His leadership qualities are obviously another huge plus for us – he’ll be a big voice for us, someone who drives the team on from the middle of the pitch.

“We’re excited to get him up and running, for what will be another busy season on both the domestic and European front.”
