Consistency is a trait that supporters have come to expect from the club legend, and that has once again been apparent over the course of the last nine months.
The Finnish stopper, who moved to the club from his homeland in 1997, was rewarded for his loyalty with a testimonial, which took place against Scottish outfit Hibernian a week before the season started.
Jaaskelainen has started in every one of the Premier League fixtures and also played his part in Wanderers' quest to the fifth round of the FA Cup by saving a penalty from Tom Huddlestone in the televised tie at the Reebok.
Jaaskelainen is sure to be remembered as one of the best pound-for-pound signings in Wanderers' proud history after a remarkable stint as the club's undisputed number one.
The long-serving goalkeeper was a relative unknown when he joined the club from VPS Vaasa in 1997 for what was a bargain £100k fee.
He was rewarded for his loyalty to the club with a testimonial against Hibernian just prior to the start of the 2009/10.
