The France international striker has signed a four-year contract.

The 27-year-old played in the Premier League for Newcastle last season while on loan from QPR. He returned to Loftus Road in the summer.

On signing for the Blues, he said: 'I feel very happy and very proud. When I heard Chelsea wanted to sign me I said "let's go" straight away because they are one of the best clubs in the world. I remember the amazing atmosphere at Stamford Bridge when I played there for Marseille and I can't wait to play for the first time in front of my new fans.'

Remy, who is 6ft tall, is renowned for his pace, eye for goal and a versatility which has also allowed him to succeed in wide positions.

He is one of an illustrious list of players to have come through Lyon’s youth academy. He made his first-team debut for his home-town club in 2006 and played for them during two Ligue 1 title-winning seasons, as well as experiencing the Champions League.

However, it was at Nice, following a loan spell at Lens, where the young Remy truly began to build his reputation.

The goals flowed fast, earning a move along the south coast to Marseille, signed by former Chelsea player and current France manager Didier Deschamps in August 2010. He scored his first Champions League goals during his opening season for Marseille and played in two group games against Chelsea. He was their top league scorer with 15 goals in 2010/11 as well as finding the net for the first time for France that season, having made his international debut in June 2009.

With Remy having averaged almost a goal every two games during two and a half years at Marseille, the Premier League came calling in January 2013 and he scored on his QPR debut at West Ham. Of his six goals in 14 games before the end of that campaign, it was a first-time smash from outside the area against Wigan that most caught the eye. However with Rangers relegated from the top flight, he was loaned for 2013/14 to Newcastle.

A goal against Chelsea at St James’ Park in November was one of 14 he scored in the Premier League last season, helping to earn a place in France’s squad for Brazil in the summer, where he made two substitute appearances.

He played in QPR’s first two league games this season but not in their Capital One Cup defeat by Burton Albion, so remains eligible to play for Chelsea in all competitions.
