Galatasaray winger Bruma has a host of Premier League clubs chasing his signature.
Bugun says Chelsea boss Jose Mourinho is keen to secure the services of the 19-year-old but faces stiff competition from Everton, QPR, Stoke City and West Ham United.
Everton boss Roberto Martinez is rumoured to have offered the Turkish club a loan offer with a £12m purchase option at the end of the temporary spell.
Chelsea are known to be scouting young talent across the continent but it is thought that Galatasaray would rather loan the player out as opposed to losing him on a permanent basis.
