Romelu Lukaku returned to Chelsea on Thursday for a reported club record fee of £97 million ($135 million) from Inter Milan, seven years after his first spell at Stamford Bridge came to an end.
The Belgian striker was instrumental in securing Inter's first Serie A title for 11 years last season, but the Italian giants financial problems forced them into selling their prized asset to the Premier League side.
"The way the club is going fits my ambitions perfectly at 28 and just coming off winning Serie A. I think this opportunity comes at the right time and hopefully we can have a lot of success together."
Lukaku scored 64 goals in two seasons in Italy to quickly become a hero at the San Siro.
But the 28-year-old also has a proven record in the Premier League, scoring 113 goals during spells with Manchester United, Everton and West Brom.
