I suppose this sounds rather obvious, but last year, injury seriously disrupted the popular Irishman's campaign. Having just returned from a broken leg, he rode Footpad to an almighty victory in the Racing Post Arkle before winning the Mares on Benie Des Dieux. However, he aggravated his leg once more, when Al Boum Photo fell the following day in the RSA Chase which subsequently ruled him out for the rest of the festival.
Ruby is now back, and any Mullins horse - or any horse for that matter, always has a chance with Ruby aboard. With 58 Cheltenham winners to his name, he is one of the standout stars of the jump season. With an injury-free season, many would expect him to be the leading jockey at the festival once more - a feat he sustained five times in a row between 2013 and 2017. Many would argue, he is one the best jump jockeys of all time.
