[44] Afterwards, Jääskeläinen regained his first choice goalkeeper role, with local newspaper The Bolton News, stating that: "On the form he is showing at the moment, it's hard to see Jaaskelainen being ousted by either Keith Branagan or Steve Banks, when they are fit again.

[197] In a semi–finals of the FA Cup match against Stoke City on 17 April 2011, Jääskeläinen conceded five goals, as Bolton Wanderers loss 5–0 and prevented his dreams of playing in the final once again.

[232] Jääskeläinen played a contributing role for West Ham United when he kept a clean sheet in a "vital win" against Tottenham Hotspur to climb out of the relegation zone on 6 October 2013.
"[234] Jääskeläinen played just one game for West Ham in the 2014–15 season, coming on for Carlton Cole after Adrián had been sent-off in a goalless draw at Southampton on 11 February 2015.
