did well enough to retain his place. Once again, speculation about Bopp's future arose as he struggled to maintain his place in the squad, and on 7 May Crewe announced that Bopp's contract had been terminated by mutual consent. Trial at Portsmouth Bopp was included in the Portsmouth squad for the first 2009–10 pre-season friendly away to Havant and Waterlooville. Bopp played the entire second half and scored both of Portsmouth's goals in a 2–2 draw. After an injury crisis, Portsmouth were eager to sign Bopp ahead of a Premier League match against Wigan Athletic on 31 October. However, the Premier League refused to register the player because of Portsmouth's debts and a transfer embargo was placed on the club. Bopp continued, however, to play games for the reserve team. Carl Zeiss Jena Bopp signed with German 3. Liga club Carl Zeiss Jena on 7 December 2010. Bopp played his debut for Carl Zeiss Jena in the match on 11 December against Dynamo Dresden. He made 16 appearances for the club before he was released in June 2011. York City Bopp returned to England after signing for Conference Premier club York City on a contact until the end of the 2011–12 season on 22 March 2012. His debut came as a 69th-minute substitute for Jon Challinor in a 2–1 victory away at Luton Town on 30 March 2012, before dislocating his shoulder on his full debut in his following appearance, a 1–0 defeat at home to Fleetwood Town on 7 April 2012. This ruled him out for the rest of the season, which York finished with promotion to League Two through the play-offs. Having made two appearances he was released by York on 3 July 2012. Later career In the summer of 2014, after two years of being unattached, Bopp went on trial at League Two side Hartlepool United. A year later he came out of retirement to sign for Midland League Premier Division club Dunkirk as a player-coach during June 2015. Bopp joined Basford United of the Northern Premier League Division One South in October 2015, as part of a swap deal with Dan Fletcher. International career Bopp was capped twice by Germany at under-19 level, making his debut as a 65th minute substitute in a 4–0 victory over Sweden on 4 September 2001. His second and final cap came after starting a 2–2 draw with Turkey on 11
