Freddie Head is expecting a big run from Naaqoos in the Prix Jean Prat at Chantilly on Sunday.Last season's top two-year-old has yet to hit the heights this term, though his second place to subsequent French Derby winner Le Havre on his return, followed by his demotion to sixth from third in the French 2000 Guineas, bears inspection."He's a very good horse. He was third in the French 2000 Guineas last time and was very badly demoted, but he is very well," the French trainer told At The Races."He was the champion two-year-old after winning the Prix Jean-Luc Lagardere. To be beaten by the Derby winner is pretty good and he's going to run in the good races - he's never had a bad race."I don't think he will get much more than a mile, but he is very effective over that trip. He was very keen that day in the Guineas. He came with a good chance and just stopped a bit in the last 100 yards."I think he has a first-class chance on Sunday."
