The Shiraz Sunderji-trained Collegium, who registered dramatic improvement over his debut run when filling up the frame behind Tutankhamun, is expected to be the most in demand in the Hong Kong Jockey Club Trophy, the feature event of Wednesday's eight-race evening card at Mahalaxmi.

However, he may face stiff challenge from first-timer Mygrator (A Sandesh up), and the Shorff-trained Manifold (Neeraj Rawal up) who is due for improvement in second lifetime start.
