After the race winning jockey Donnacha O'Brien said of Saxon Warrior: "He's a very good horse, he's a proper horse."[1]
The Aidan O'Brien trained colt Gustav Klimt became an early ante-post favourite for the race after winning the Superlative Stakes at Newmarket in July 2017,[3] but after an impressive win in the Vintage Stakes at Glorious Goodwood, Sir Michael Stoute's Expert Eye then took over as the market leader.[4] Stoute stated it was "too early to tell if he's a Guineas horse" but jockey Andrea Atzeni was more positive, saying, "I don’t think I’ve ever sat on a two-year-old as good as this".
