Lulamba lived up to the hype when he comfortably accounted for fellow French import Mondo Man in the BetMGM Juvenile Hurdle at Ascot.
Nicky Henderson's charge scored five lengths in a 16-runner contest at Auteuil on his racecourse debut after being the subject of glowing reports since arriving at Seven Barrows.
Mondo Man was bought for €520,000 after showing plenty of ability on the Flat, notably finishing fifth in the French Derby and fourth behind Calandagan in the King Edward VII Stakes at Royal Ascot.
The Gary and Josh Moore runner ran at the back early on, while Nico de Boinville took a comfortable position on Lulamba following Viyanni.
Caoilin Quinn allowed Mondo Man to make a move in front by three furlongs but Lulamba always traveled well and the 4/5 favorite went smoothly to the front in the home straight before scoring by three and a half lengths.
The winner has been reduced to 6/4 for Triumph Hurdle glory at Cheltenham by Betfair, Coral and Paddy Power.

Winning rider Nico de Boinville believes there is a huge improvement ahead of Triumph Hurdle favorite Lulamba after success on his British debut at Ascot.
Don't risk it continued strongly to upend hot favorite Kargese in the Grade 2 BetMGM Mares' Hurdle.
The Willie Mullins-trained Kargese had her first outing after completing a superb juvenile campaign by securing a second Grade One success at the Punchestown Festival last May.
However, the 2/5 market leader traveled sweetly under Paul Townend and looked set to prevail when he moved to challenge Ooh Betty at the other end.

Take No Chances (13/2) didn't read the script though and produced a determined surge to jump to the front in the final furlong before fighting back to beat Karges by three-quarters of a length.
The Dan Skelton-trained winner posted a career-best performance in victory, with winning jockey Kielan Woods praising her consistency, as her 15-race career has produced four previous wins as well as a string of placings.
