The Brazil under-23 forward will spend his fourth successive year on loan away from Stamford Bridge after joining the Championship outfit until the end of the season
Chelsea attacker Lucas Piazon has agreed a season-long loan deal with second-tier Reading.
The 21-year-old, who has featured just once for the Blues since his move from Sao Paulo in 2011, will join up with former Chelsea player and coach Steve Clarke, now in charge at the Madejeski Stadium.
The Brazilian spent last season on loan at Bundesliga outfit Eintracht Frankfurt and has picked up further experience of European competition with previous short-term deals with Vitesse in the Netherlands and with La Liga’s Malaga.
The youngster made 23 appearances in Germany last year and scored on two occasions.
