El Hadji Malick Diouf, a 21-year-old Senegalese defender, has signed a five-year contract with Brentford, with an option for a further year. He joins the Bees after just one season at West Ham, where he made 34 appearances. Diouf was signed by West Ham from Slavia Prague for £22 million last summer. Brentford have now spent around £41 million on the defender, making him their fifth major signing of the summer. This deal comes after West Ham's recent transfer of Mateus Fernandes to Tottenham for £98 million and Crysencio Summerville to Al-Hilal for £70 million.
