"You saw it last season, in the seasons before at Juventus and with Italy as national coach".
Chelsea did get Germany centre-back Antonio Rudiger, back-up keeper Willy Caballero and Monaco midfielder Tiemoue Bakayoko, who arrived for £40m yesterday.
The striker is known for his outstanding pace, which would fit in with Chelsea's rapid counter-attacking style that they have adopted under Conte and his preferred 3-4-3 formation.
"I'm very happy to be here", he told the Blues' official website. The deal looked to be good value the day it was announced and proved to be a bargain. And the club's hopes of successfully defending their title have taken a huge blow by his pending departure, as there are no guarantees that whoever replaces Costa will manage to have the same impact on the Premier League.
The 28-year-old has been told by Conte that he is not in his plans for next season, and the Spain global has made no secret of his desire to rejoin his former club in the Spanish capital.
They have made an initial bid of £28million to sign the Brazilian. Despite frequently exasperating fans with his inconsistent first touch and impetuous tackling, he will always enjoy hero status at Stamford Bridge because of his sensational lob at Camp Nou against Barcelona on the Blues' miraculous run to Champions League glory in 2012.
