Belgium teenager Romelu Lukaku declared it was a dream come true after completing his transfer to Chelsea from Anderlecht.
The London club confirmed on their website Thursday that the deal had been finalised after the two clubs agreed a fee, thought to be between £15-20million, for the highly-rated 18-year-old striker earlier this month.
He underwent a medical at the Blues' training ground in Cobham last week and will now be available for Saturday's Barclays Premier League game against West Brom.
"Amazing. It's a dream come true,'' he said on www.chelseafc.com.
"I dreamed to play here since I was 10 years old, thinking about shaking hands with all those players like John Terry and Frank Lampard and Didier Drogba.
"It's amazing to arrive here in a big club with big ambition. It was just what I was searching for.''
