Manuel Pellegrini has been named as the new manager of West Ham.
The 64-year-old Chilean has signed a three-year deal at the London Stadium.
Pellegrini, the former boss at Manchester City and Real Madrid, left his position at Hebei China Fortune over the weekend and succeeds David Moyes.
Pellegrini said: "I am excited about this project. My mentality is always to have a winning mentality.
"I think that West Ham had a difficult season last season and I hope that next season we are going to play football that will delight the fans. I always play attacking football and we must try to reach important targets in the season.
"I am sure that, with the players we have in this moment in the squad, and bringing maybe another four or five in, we are going to have a strong team."
Moyes was released from his short-term contract after West Ham finished 13th in the league.
