Example Input: Question: Which Bristol City F.C. manager that Goodfellow played for had a longer tenure with the club? Passage:He made only a handful of appearances at the Britannia Stadium in 2003–04, though he earned a £50,000 move to Bristol City in the January transfer window. He played in the play-off final defeat to Brighton & Hove Albion, replacing defender Tony Butler on 88 minutes as manager Danny Wilson made a late attempt to save the game. He did not feature heavily at Ashton Gate and instead was loaned out to Port Vale in October 2004. The next month Swansea City manager Kenny Jackett was on the lookout for a quality winger, Goodfellow meanwhile was prepared to go out on loan to the League Two club. Jackett managed to persuade City to allow Goodfellow to join the "Swans" on loan. He impressed at the Welsh club and his loan spell was extended the following month. However, he was quickly recalled to Ashton Gate after a spate of injuries at the Bristol club. Soon after Swansea attempted to buy Goodfellow off City, however, City manager Brian Tinnion informed Goodfellow he still had a future at the club. Tinnion was expecting at least what they paid Stoke for him and Swansea were unable to comply. In March 2005 he joined Colchester United on loan until the end of the season and scored once against Peterborough United.
