Nicky Henderson is under no illusions about the task facing Jonbon as he bids turn the tables on Il Etait Temps in the BetMGM Clarence House Chase at Ascot on Saturday.

The JP McManus-owned Jonbon claimed his ninth Grade One victory in this race 12 months ago and moved up to double figures by successfully defending his crown in the Melling Chase at Aintree over two and a half miles in the spring.
