Sporting winger Geovany Quenda has been carrying out much of his recovery from a fractured metatarsal at Chelsea's training ground.
The 18u2011yearu2011old has been given access to Chelsea's worldu2011class facilities at Cobham and the chance to familiarise himself with his future club ahead of his summer move.
Quenda hopes to return to the pitch in March, having sustained the injury in early December during a match against Benfica.
That return would see him feature in Sporting's upcoming Champions League lastu201116 ties and his side are also competing for the Portuguese title and sit four points behind leaders Porto in second place.
