Cheltenham Gold Cup hero Synchronised heads a maximum field of 40 for the John Smith's Grand National at Aintree on Saturday. 

Tony McCoy's mount, trained by Jonjo O'Neill, will bid to become the first horse since Golden Miller in 1934 to win the Gold Cup and Grand National in the same season. 

All the other leading fancies are in the final line-up, including last year's winner Ballabriggs, trained by Donald McCain. 

On His Own, the mount of Ruby Walsh, heads Willie Mullins' team while the Irish jockey's sister Katie will be aboard Seabass for their father, Ted Walsh. 

Nina Carberry, who is also bidding to become the first female rider to win the race, will be aboard Organisedconfusion for her uncle, Arthur Moore. 

Among the other major contenders are Giles Cross, West End Rocker, Junior, Cappa Bleu, Chicago Grey and Killyglen. Le Beau Bai has been withdrawn, while Always Waining will run in Friday's Topham Chase.

Four reserves were declared - the first reserve being Any Currency followed by Our Island, Abbeybraney and Smoking Aces. They have until 9am on Friday morning to get a run.
