The former Queens Park Rangers forward has been handed the no.18 shirt at Stamford Bridge.

The Frenchman swapped one west London side for another just a few days ago, in a move that saw Jose Mourinho's side part with £8 million to acquire Remy's services.
And the 27-year-old will wear no.18 on his back when he turns out at Stamford Bridge this season.
It may just sound like a boring old number - but Chelsea fans can draw two conclusions from the confirmation.
First, Remy takes the shirt Romelu Lukaku held at the Blues. Secondly, Victor Moses will need a new shirt number if he returns to Chelsea.
The Nigerian international was given the no.18 shirt when Lukaku was sold to Everton for £28 million this summer but has since moved on loan to Stoke City.
Remy arrives at Stamford Bridge to provide backup for Diego Costa, with Didier Drogba completing Mourinho's set of strikers at Chelsea.
The 27-year-old's signing became a priority for the west London club when Fernando Torres joined AC Milan on a two-year loan deal very late in the transfer window.
Remy scored 15 goals while on loan at Newcastle United last season, while impressing during his time at QPR before that.
