Chelsea have completed the club record £60m signing of striker Alvaro Morata from Real Madrid on a five-year deal.
The Spain international, 24, scored 20 goals last season after rejoining Real from Italian champions Juventus.
Morata won La Liga and the Champions League, but the majority of his appearances were as a substitute.
Premier League champions Chelsea have also signed goalkeeper Willy Caballero, defender Antonio Rudiger and midfielder Tiemoue Bakayoko this summer.
Morata will now join up with the Blues squad on their pre-season tour of Asia.
Chelsea’s previous transfer record was the £50m they paid Liverpool for Fernando Torres in January 2011.
“Alvaro has proven class at the highest level and his quality will be a huge asset,” said Chelsea technical director Michael Emenalo.
