Promising young striker Luis Cumbers joined the Gills as a trainee in July 2006 and made his League debut in the 2-0 home defeat by Yeovil in May 2007. in 2007/08 he made a further six league appearances for the club and also enjoyed goal scoring loan spells with Maidstone United and Grays Athletic.

Luis finished that season on loan at AFC Wimbledon helping them achieve promotion to Blue Square South with a goal in the Ryman League Premier play-off final.

Cumbers began the 2008/09 season with a lively spell in the Reserves, scoring a brace in both of his opening outings for the side. Injuries limited his first team appearances to just seven league outings but he did manage to claim his first goal for the club in the 4-0 demolition of Rotherham.

He ended the season with a loan spell at Blue Square Premier Ebbsfleet before agreeing a new one year deal for 2009/10. Luis returned to Ebbsfleet for a second spell at the start of the season and is now on loan again at AFC Wimbledon.
