Input: Question: Did Swan play in more games for Hull City or Port Vale? Passage:He began his career with local side Leeds United in 1984, before he moved on to Hull City for £200,000 in 1989. Two years later he transferred to Port Vale for a fee of £300,000. He spent three years with Vale, before he was sold on to Plymouth Argyle for the same price. During his time at Vale Park he was selected in the PFA's Second Division team of the season in 1992–93, before he won promotion out of the division in 1993–94; he also won the TNT Tournament in 1992 and the Football League Trophy in 1993 with the club. However at Plymouth he failed to find success, and was instead transferred to Burnley for £200,000 after just twelve months. In 1997, he signed with Bury for £50,000, before he returned to Burnley as a free transfer signing the following year. In 2000, he joined York City, before he retired later in the year.
