Sizing Europe advertises his Champion Chase credentials by slamming Big Zeb at Punchestown Lynch, whose career took off after he started riding Sizing Europe for De Bromhead, said: "The plan was to go out and enjoy ourselves and he's done it well. I wanted to make the most of the big stride on him. The ground is a bit tacky but he's a bit stronger now and handles it better than he used to. He hadn't run since the Tingle Creek so he should improve a bit for that. Colm Murphy, Big Zeb's trainer, blamed the ground. "Robbie was never happy with him today," he explained. He said he was beaten before the first and was always niggling just to keep in touch. The winner was very good, he's gone a proper gallop on heavy ground. We'll improve for the run but we'll need to. Cheltenham's still the plan. With the best of the home team looking like Finian's Rainbow, who was beaten by Somersby at Ascot fortnight ago, it increases the chances - and, as far as bookmakers are concerned, a worst-case scenario - of last year's four major Cheltenham champions all defending their titles. Victor Chandler originally offered 50-1 about the chances of that but with Big Buck's (World Hurdle), Hurricane Fly (Champion Hurdle) and now Sizing Europe all looking good, last night they were offering 22-1. Only Long Run (Gold Cup), who is due out in the Denman Chase at Newbury on Saturday, has made yet to make a convincing case for himself. "If all the other three have already obliged it might be a question of layers, like everyone else, rooting for Kauto Star in the Gold Cup, although it will only be the lesser of two evils," said Charlie McCann, of Victor Chandler. 22-1 The odds offered by Victor Chandler against Big Zeb, Big Buck's, Hurricane Fly and Long Run repeating last year's victories in the four big races at the Cheltenham Festival next month. The BHA will consider putting on extra fixtures this week to negate the loss in Levy income caused by the cold snap. Also on the agenda will be the restaging of the Scilly Isles Novice Chase, Sandown's Grade One novice chase which was lost on Saturday. Musselburgh will also put in a request to restage the valuable card lost on Sunday.
