West Ham majority shareholder David Sullivan has responded to reports on the contract situation of midfielder Manuel Lanzini.
The Argentine playmaker has scored three goals in 10 Premier League appearances for the Hammers since joining on loan from Abu Dhabi-based club Al Jazira, along with some impressive performances of late.
"I know there have been some reports in the media over the weekend surrounding the future of Manuel Lanzini," Sullivan wrote on the club's official website.
"We have an unbreakable option with both Lanzini and his club, so any other team's interest is irrelevant.
"Manuel has been a fantastic signing for the club and we all hope he can maintain this superb run of form for the rest of the season."
Those West Ham players not on international duty will be preparing for their next Premier League encounter against Tottenham at White Hart Lane on Sunday.
"We have had some amazing results away from home this season against some of the biggest teams in the country and I am sure the fans would love to see us pick up another memorable victory this weekend," Sullivan added.
