Robert Walpole Sealy Vidal, who from 1892 was Robert Walpole Sealy (3 September 1853 – 5 November 1914) was a prominent 19th century footballer who featured in the first three FA Cup Finals for two different clubs. In March 1870 he played in the first ever international football match, which took place at Kennington Oval, London. He represented England again in 1871.
Vidal was born at Cornborough House, Abbotsham near Bideford, Devon, England, and educated at Westminster School, being Captain of School and of the School's football and cricket XIs when he left in 1872. He entered Christ Church, Oxford where he graduated as B.A. in 1876 and M.A. in 1879.
Vidal was well known as the "prince of dribblers". In those days, the rule was that the team that scored also kicked off afterwards. On one occasion this rule allowed Vidal to score three goals in a match without the other team touching the ball. He played in the first three FA Cup Finals, of 1872, 1873 and 1874. He was a member of the Wanderers F.C. team when they won the first ever FA Cup. It is said that he assisted the first FA Cup Final goal when, 15 minutes into the match, Vidal broke away and looped the ball across to Morton Betts, who shot between the posts. At 18 years 195 days he was the youngest ever player in a Cup Final until surpassed by 17 years old James F. M. Prinsep in 1879, and only winning player still at school on Cup Final day.
