Łukasz Marek Fabiański (born 18 April 1985) is a Polish professional footballer who plays as a goalkeeper for Premier League club West Ham United.

Having begun his career at Legia Warsaw, Fabiański joined Arsenal for £2.1 million in 2007, and was mainly used as back-up, but played as the club won the 2014 FA Cup final.

[6] On 8 May 2007, Fabiański underwent medical tests in London after Arsenal agreed a transfer fee with Legia Warsaw worth approximately £2.1 million.

He was criticised for conceding soft goals in the defeats to Wigan Athletic and Blackburn Rovers, but kept clean sheets in the matches at home to Manchester City and Fulham.

On 21 September 2010, he made his first start of the season in a League Cup match against neighbours Tottenham Hotspur at White Hart Lane, which Arsenal won 4–1 after extra time.

[21][22] However, he produced a strong display to keep a clean sheet in the next Premier League match, against Wolverhampton Wanderers, in which he managed to prevent a draw with a last-minute save, and then initiating a counter-attack with a long throw of the ball that led to another Arsenal goal.

[citation needed] Fabiański spent the 2011–12 season as backup to Wojciech Szczęsny, making his first appearance against Shrewsbury Town in the League Cup.

[citation needed] On 6 December 2011, Fabiański was selected to start in Arsenal's UEFA Champions League group stage match against Olympiacos, but was substituted out after 25 minutes following a knee injury.

In March 2013, after Szczęsny was dropped, Fabiański started in goal in the second-leg of Arsenal's UEFA Champions League tie against Bayern Munich.

[citation needed] On 19 February 2014, Fabiański came on as a substitute in the 37th minute of a 2–0 Champions League home defeat against Bayern Munich, after Szczęsny was sent off for a foul on Arjen Robben.

[28] On 12 April, Fabiański saved penalties from Gary Caldwell and Jack Collison in an FA Cup semi-final shootout victory over Wigan Athletic.

[29] He made his only Premier League appearance of the season in the last match on 11 May, keeping a clean sheet in a 2–0 away win that caused his opponents Norwich City to be relegated.

[31] On 29 May 2014, it was announced that Fabiański would join fellow Premier League side Swansea City on a free transfer when his Arsenal contract expired on 1 July.

[48] Having represented Poland regularly at under-21 level, Fabiański's performances for Legia Warsaw saw him soon making his debut for the senior international team in a friendly against Saudi Arabia on 29 March 2006.

[53] He was also included in the team's squad for the 2018 FIFA World Cup finals, although Szczęsny was chosen over him to start the first two group matches, where Poland suffered losses to Senegal and Colombia.

Fabiański started the final group match against Japan to make his only World Cup appearance, keeping a clean sheet in Poland's 1–0 win, which proved to be too little to prevent the team's elimination from the tournament.

[54] He was also included in Poland's squad for the UEFA Euro 2020, but made no appearances as the team suffered another early elimination after only scoring a point in their three group matches.

[57][58] Fabiański started the game and was substituted in the 57th minute by Radosław Majecki of the eventual 5–0 home win, officially ending his international career with 57 caps.
