He joined Torquay United on loan in March 1992 and signed on a free transfer for the Plainmoor side that summer. after 106 league games and 16 goals for Torquay, he was a regular under manager Don O'Riordan and started to attract Premier League clubs and moved to Derby County in December 1994 for a fee of £100,000. He had loan spells with Grimsby Town in August 1996 and Crystal Palace in October 1996. He moved to Fulham in November 1997 for a fee of £600,000.

However, he left the Cottagers to join Coventry City on a free transfer in March 2002 after losing his place at Craven Cottage. He stayed only a few months at Highfield Road, moving to Northampton Town in July after being released at the end of the season.
International career
In May 1997, Trollope was called up by then Wales manager, Bobby Gould, and made his debut in a 1–0 victory over Scotland at Kilmarnock. While Trollope was never able to hold down a regular place in the Welsh international team, he made nine appearances for the senior squad over six years, culminating in March 2003 in a 4–0 home victory over Azerbaijan in the ultimately unsuccessful qualifying campaign for Euro 2004.
Management career
Bristol Rovers
In June 2004 he moved to Bristol Rovers on a free transfer. In his second season, he became caretaker manager and was then appointed first-team coach in a two-tier managerial structure, alongside Director of FootballLennie Lawrence, in November 2005. His first season in charge ended in a respectable midtable position of 12th place in League Two. The following year Rovers reached the Football League Trophy final but lost to Doncaster Rovers. They made up for this loss by winning promotion to League One via the play-offs. In the 2007–08 season, Trollope steered Bristol Rovers to mid-table security after a shaky start. Rovers also made the quarter-finals of the FA Cupfor the first time in 50 years. In September 2009, following more success, he signed a rolling one-year contract under which his title changed to manager. Despite his achievements at the club, he was sacked on 15 December 2010, with Rovers lying inthe League One relegation zone. His overall record in charge of the club was 106 wins and 71 draws from 284 games.

Trollope was appointed head coach of Championship club Cardiff City in February 2015. On 21 July 2015, Trollope was appointed as a coach for the Welsh National team alongside his role at Cardiff City.

Slade later resigned from his role, after just two weeks, on 3 June. After a poor start to the season, winning 2 of his opening 12 matches, Trollope was sacked by the club on 4 October 2016.
