West Ham United have officially announced on Twitter the signing of Sofiane Feghouli on a three year deal from Valencia.

The 26-year-old Algerian international will join on a free transfer after failing to agree a new contract with the La Liga team.

Feghouli, who was a regular for the Spanish side last season, was also linked with the likes of Manchester United, Tottenham Hotspur and Inter Milan in recent weeks.
