Romelu Lukaku has taken part in Manchester United training for the first time as the £75million man worked up a sweat in the Los Angeles sunshine.
Lukaku was unveiled as a United player on Monday as he became the world's most expensive striker following his move from Everton.
And it was straight to work for the Belgian, as he immediately linked up with his new team-mates for a session in sunny California.
