"[4] On 11 March 2005, due to an injury to Carl Muggleton, he joined League One club Chesterfield on a month's loan,[5] making his English debut in a 2–1 home win over Huddersfield Town the following day.

In early 2006 he stated that he did not intend to stay at Tottenham as he admitted it would be hard to get past number one Robinson, and expressed a desire to join Coventry in a permanent move.

[11] Fülöp signed a year-long loan deal with Leicester City of the Championship on 16 August 2007,[12] making his debut against Crystal Palace two days later, which ended in a 2–2 draw.

[15][16] Fülöp made another fine performance against Chelsea in another League Cup match on 31 October, twice denying Claudio Pizarro and pushing an effort from Scott Sinclair onto the post, but could not prevent his side from losing 4–3 at Stamford Bridge.

Fülöp told Sky Sports on 21 December that he was interested in a permanent deal with Leicester,[18] and the club made an offer for him eight days later, together with Graham Kavanagh.

[21] On 4 January 2008, Leicester manager Ian Holloway accused Sunderland counterpart Roy Keane of being greedy after his initial bid to sign Fülöp was rejected.

[23] Fülöp was loaned to Stoke City on 22 February 2008,[24] but was recalled by Sunderland just four days later as back up cover to Craig Gordon following Darren Ward's injury, making one appearance in the final Premier League game at home to Arsenal.

After staying for one season with Ipswich Town, Fülöp signed a one-year contract with West Bromwich Albion on 6 August 2011,[33] moving on a free transfer.

[39] Fülöp made his full international debut for the Hungarian national team on 31 May 2005, coming on at half-time for Gábor Király against France in a friendly at the Stade Municipal Saint-Symphorien in Metz.

[42] On the day of his death, Hungarian internationals, wearing black armbands, won 1–0 away to the favoured Norway team in the first leg of their UEFA Euro 2016 qualifying play-off game.

[45] When with only two minutes remaining from the game, Norway's Pål André Helland headed a rebounding ball against the crossbar with an open goal gaping, Hungarian commentator István Hajdú B. remarked: "This was probably tipped to the bar by Márton Fülöp...this was a helping hand from the sky".

[46] Three days later, the rematch in Budapest started with a minute's silence in the memory of him (as well as former Golden Team member Pál Várhidi and the victims of the Paris terror attacks).

[47] Several players commemorated Fülöp in their post match interviews, including goalscorer Tamás Priskin who paid tribute by dedicating his goal to his late teammate.

[49] On 14 June 2016, before Hungary's first Euro 2016 match, the three goalkeepers of the Hungarian squad, Király, Dénes Dibusz and Péter Gulácsi, were noticed while being photographed together during the pre-game field walk, holding a pair of keeper gloves labelled with Fülöp's name.
