The Pole has rebuilt his reputation at Swansea since claiming their number one spot, following a terrible start to his career in England with Arsenal.
At the Gunners he was error prone and indecisive, and looked like he would make a mistake every time the ball came near him.
Some of this can be attributed to nerves, playing in England for the first time, but another factor was also in play... pressure.
At Arsenal the spotlight was intense, especially with competition for his place fierce at the time.
Since moving to Swansea City, Fabianski has had it a lot easier, despite the team's battle with relegation.
His every move was not scrutinised, and any errors he made were not highlighted.
At West Ham, the pressure will be back on, and their fans are every bit as anxious as Arsenal's for success.
Fabianski must prove that the spotlight on his performances does not cause him to revert to type, and take a big step backwards in his career with his performances.
