2013/14 English Premier League
After initial promise, Lukasz Fabianski's career stalled at Arsenal, with his errors casting a shadow over his time at the club despite the backing of manager Arsene Wenger.
Having begun his career in the MSP Szamotuly football academy when he was 14-years-old, he played for three small Polish clubs before signing for Lech Poznan in the 2004-05 season. Grabbing the attention of Legia Warszawa, Fabianski was signed and competed with Artur Boruc -- who would later move to Celtic -- going on to help Legia win the Polish league championship in the 2005-2006 season.
With some exceptional performances, he won the Football Oscar for the best goalkeeper in the Polish Ekstraklasa in both the 2005 and 2006 seasons, catching the eye of Arsenal. However, despite being given a chance to shine, the Pole regularly erred when elevated to the first-team -- with mistakes against Porto, Wigan, Blackburn and Stoke putting him in the spotlight.
International compatriot Wojciech Szczesny displaced him as Arsenal No. 1 halfway through the 2010-11 season, although he did enjoy another rare spell in the side during the 2012-13 campaign, keeping back-to-back clean sheets against Bayern Munich and Swansea before a rib injury forced him to return to the bench soon after.
The signing of Emiliano Viviano ahead of the 2013-14 season saw Fabianski faced with yet more competition in North London.
Strengths: An agile goalkeeper, he gets around his area and has excellent reflexes.
Weaknesses: Suspect from crosses, his decision making has been questioned and his mental fragility has been highlighted. With low confidence levels, he can be a liability in goal.
Career high: Keeping Bayern's eventual Champions League winners at bay in the 2012-13 last-16 second leg at Allianz Arena.
Career low: A number of errors with Arsenal saw him criticised in the media, and his display against FC Porto in the Champions League saw him hit an all-time low.
Style: Agile, athletic, but there are questions over his mental strength.
Quotes: "I am personally convinced he is a world-class goalkeeper, potentially, and of course when you have that potential you want to transfer that into competitive games. I have massive faith in him and I think I have shown this historically. I am convinced he will become a great goalkeeper.'' Arsene Wenger, September 2010.
Trivia: The Pole earned himself the nickname of 'Flappyhandski' for his mistakes at Arsenal.
