Lulamba has 'so much untapped potential' says the man responsible for buying him from France - plus updates on Sir Gino and Jango Baie

Jerry McGrath, who was responsible for purchasing Lulamba from France, believes the sky is the limit for the leading Arkle contender after his stylish success in Grade 1 company at Sandown on Saturday.

The four-year-old made it four wins from five starts since joining Nicky Henderson last year when beating Be Aware by nine and a half lengths in the Grade 1 Henry VIII Novices' Chase. It was a performance that prompted bookmakers to shorten him into 5-2 second favourite for the Arkle, behind 2-1 market leader Kopek Des Bordes.

McGrath, who has enjoyed a successful spell as a bloodstock agent since retiring from the saddle due to injury in 2022, was in attendance at Sandown as he continues to play a pivotal role at Seven Barrows and was impressed with Lulamba's latest Grade 1 triumph.
