Eisfeld started his career at the famed Borussia Dortmund youth academy – just like Germany internationals Mario Götze, Kevin Grosskreutz and Marco Reus.
In fact, he once captained Dortmund’s Under-15 team.
Thomas went on to represent Germany at Under-20 level.
His performances caught the eye of a number of Europe’s top clubs, particularly serial talent-spotter Arsene Wenger who signed Thomas for Arsenal in January 2012.
He made his professional debut against Reading in the League Cup in October 2012, coming off the bench in the Gunners’ 7-5 extra-time win.
He scored his first goal for the north London club during the 2013/14 season, netting in the League Cup defeat of West Bromwich Albion. Arsenal went on to beat the Baggies 4-3 on penalties.
During his time at the Emirates, Thomas was often compared to former Arsenal legend Robert Pires.
He describes English football as “quick and full of energy”. He believes the style suits his game.
In July, Eisfeld signed a two-year deal with an option for a further 12 months with the Whites.
Eisfeld will wear the No.7 shirt at Craven Cottage. Steve Sidwell – now at Stoke City – wore the number last season.
Last season, the player scored for Arsenal in a 1-0 win for his former club’s Under-21s against Kit Symons’ young charges at Motspur Park.
He shares his birthday, January 18th, with Bayern Munich manager Pep Guardiola and QPR goalkeeper Robert Green.
