Chelsea launched Xabi Alonso's home managerial career in style, defeating Brighton & Hove Albion 4-3 in a breathless match that extended their winning run at the start of the new season.

The seven-goal thriller at Stamford Bridge gave Alonso a perfect introduction to the home faithful, with Chelsea proving too strong for a Brighton side that refused to go quietly despite the heavy scoreline.

The result means Chelsea have now won consecutive matches under their new manager, building early momentum as Alonso sets about stamping his identity on the club.
