Input: Question: When was the team founded that Grayson moved to in 1997? Passage:Grayson moved to Aston Villa in 1997 and made another 49 Premier League appearances at Villa Park, scoring two goals, both of which came in Villa's 1997–98 FA Cup campaign against Portsmouth and West Bromwich Albion. He then signed for Blackburn Rovers in July 1999, where he made 34 appearances in his first season. He lost his place in the team the following season and spent most of the next two years on loan, with spells at Sheffield Wednesday, Stockport County, Notts County (where he scored once against Reading) and Bradford City. Grayson signed for Blackpool on a free transfer on 19 July 2002. He made more than 100 appearances for the Seasiders and captained the side. He started his career at Blackpool in the right-back berth, but was moved to midfield by former boss Colin Hendry to bolster an area of weakness. In 2004 he started the final as Blackpool won the 2003–04 Football League Trophy.
