Chelsea have signed the 35-year-old striker Danny Welbeck from Brighton for a reported £5m on a two-year contract, while Brentford have made Mali international Mamadou Sangaré their record signing in a reported £39m move from Lens. Welbeck’s arrival is notable because it departs from Chelsea’s recent preference for younger recruits and reflects manager Xabi Alonso’s desire to add experience after last season’s 10th-place Premier League finish.

Welbeck scored 13 Premier League goals in 37 appearances for Brighton last season and will join Chelsea’s pre-season tour, potentially affecting the futures of Liam Delap, Nicolas Jackson and Marc Guiu. Sangaré, 24, has signed for five years with an optional extra year after helping Lens win the French Cup and finish second in Ligue 1; Bournemouth also announced the reported £25m signing of Benfica defender António Silva.
