Question: How many years was Penney a manager? Passage:After a spell at Colchester United where he scored once against A.F.C. Bournemouth, he joined Darlington at the start of the 200506 season, where he scored 10 goals in 21 league appearances. He moved to Cardiff City in January 2006, where he made 11 appearances including seven as substitute. He was released at the end of the season and signed by Gillingham. He scored his first goal for Gillingham away to Blackpool on 26 August 2006 in a game which ended 11. He struggled to hold down a place in the team during his first season at the club and was sent on loan to Bradford City the next season. He made his debut on 10 August 2007 and scored an equaliser to secure a 11 draw against Macclesfield Town. He played 18 league games, scoring six league goals for Bradford but his loan was not extended when it expired at the end of 2007 partly because of financial reasons. He returned to Gillingham but was immediately placed on the transfer list, and on 29 January 2008 he moved on a free transfer for a second spell at Darlington. Injury delayed his debut back at Darlington, which came on 23 February 2008 against Bury when he scored a sixth-minute penalty in a 21 victory. He played eight league games for Darlington, scoring three goals, and was a substitute in both legs of the play-off semi-finals against Rochdale, but after Darlington's defeat on penalties to Rochdale, he was released by manager Dave Penney. On 11 November 2010, Ndumbu-Nsungu was reported as training with Conference National side Tamworth with a view to signing. He trained with Beaconsfield SYCOB in December 2010, though the signing failed to materialise due to problems with international clearance.
