Since the 2009–10 season, Gnakpa has been utilised almost solely in a wide position, using his combination of pace, power and crossing to contribute numerous goals and assists.
Gnakpa began as a youth player for Montpellier HSC, then appeared for local sides Marignane and Beaucaire, before moving abroad to play for Racing de Santander B, Deportivo Alavés B and FC Vaduz.
In March 2007, Gnakpa was signed on transfer deadline day by Swindon Town boss Paul Sturrock on a short-term contract.
The "Flying Frenchman" was quickly made a regular at London Road and with his notoriously strong tackle and terrifying pace he cemented his place in the team.
He scored the only goal of the game in Luton's Football League Trophy area semi-final victory over Colchester United on 16 December 2008.
[7] On 5 April 2009, Gnakpa came on as a substitute and scored an extra-time winner as Luton defeated Scunthorpe United 3–2 to win the Football League Trophy final at Wembley Stadium.
