The Finnish striker, who spent the whole of last season on loan at Blues, picked up the award as recognition of his 19 goals for the club during the 2003-04 season, 17 of which were scored in Premiership games.
Blues had secured the on-loan services of the Chelsea striker for another season but after just a handful of games at the beginning of this season he was forced to undergo a knee operation which is likely to see him sidelined until April next year.
