Ange-Freddy Plumain was a winger or striker at Fulham from 2013 until 2016. He operated mainly as a winger on either flank and was signed from Lens on a free transfer in summer 2013. Although there were reports at the time of Lens accusing Fulham of signing Ange-Freddy illegally, they were proved to be unfounded and no action was taken. He made two FA Cup appearances under René Meulensteen, though these were to be the only first team outings Freddy made. He was released by the club at the end of 2015-16, returning to France and signing for Sedan.
He signed for Fulham on 25 July 2013 on a free transfer and was put straight into the Under-21 squad. Shortly after his transfer, several news reports surfaced regarding the legality of his move from Lens, stating that he was still a Lens player and that Fulham had signed him without any contact with the French club. However, these were proven to be incorrect and no further action was taken despite threats from Lens that it would be taken to court.
He made his first team debut on 4 January 2014 in an FA Cup tie away at Norwich City, after coming on to replace Alex Kačaniklić at half-time. He followed this up by featuring in the following round at Sheffield United, after being subbed on early due to an injury to John Arne Riise after 10 minutes, however he was brought off after 67 minutes despite playing well.
He enjoyed a succesful 2014-15 with the U21 squad, finishing as top scorer with 10 from 27 appearances, though it was not enough to earn him a first team call-up. In 2015-16, he was shipped out on loan for the duration of the season to Red Star in Ligue 2. On his return, he was released by the club in July 2016.
