Big guns set to clash in Queen Mother

Sizing Europe and Big Zeb, the first two home in the sportingbet.com Queen Mother Champion Chase last year, are on course for a rematch at Cheltenham next Wednesday.

The respective 2011 and 2010 winners are among 10 horses left in the two-mile feature at the confirmation stage.

Sizing Europe defeated Big Zeb by five lengths 12 months ago to follow up his win in the Arkle Trophy in 2010. And Henry de Bromhead’s stable star got the better of his old rival by 15 lengths in the Tied Cottage Chase at Punchestown last month.
