Transfers: Brentford sign Diouf from West Ham

Senegal international El Hadji Malick Diouf has joined Brentford from West Ham. The 21-year-old defender has signed a five-year deal at the Gtech Community Stadium with the option of another season. "He's a player that fits our ideal age profile, with lots of room to still develop," said Bees boss Keith Andrews. "He had a really good year at West Ham in his first season in English football, and some of the qualities and attributes he has as a full-back really add to an already impressive part of our team." Mamadou Sarr has joined Real Sociedad on a season-long loan. The 20-year-old defender, who signed a permanent deal from Strasbourg last summer, played six times for Chelsea last season.
