2006–07 season. He scored three times in 18 games, including the opener on his home debut on 17 September in a 3–2 win over Hércules. Upon returning to Molineux for training, he was challenged by manager Mick McCarthy to 'earn his transfer' to another club after no offers arrived for the striker with a year still remaining on his contract. However, he suffered a knee injury in pre-season training and was unable to attempt any action. By mutual consent, the club terminated his contract on 31 August 2007. Chicago Fire After a period of inactivity, Frankowski headed to join up with the Chicago Fire, finally signing a deal on 19 February 2008. He scored his first – and only – two goals for the club on 3 April during their home opener against the New England Revolution. However, as the season continued, his playing time greatly diminished, and he was regularly not even listed in the team's bench lineup.
