Alexander John Kosmina (born 17 August 1956), known as John Kosmina, is an Australian former football (soccer) player and manager, who is currently the Senior Coach of the Brisbane City club. He is a member of the Football Federation Australia Football Hall of Fame.
Kosmina is of Polish Australian ethnicity. He played for Polonia and then West Adelaide, before signing for English side Arsenal in February 1978. However, he only played one first-team league game for the Gunners (as a substitute against Leeds United on 19 August 1978), along with 3 appearances (2 as a substitute) in that season's UEFA cup. He returned to Australia in May 1979.
On his return, he went on to become one of the National Soccer League's most prolific scorers, with stints at Adelaide City, West Adelaide (for a second time), Sydney City, Sydney Olympic and A.P.I.A. Leichhardt Tigers before retiring in 1989. The most successful of these was with Sydney City, being part of their 1981 and 1982 championship winning teams, as well as being the league's top scorer in 1982.
After retiring, he began coaching the Warringah Dolphins in the New South Wales state leagues, before coaching NSL side Newcastle Breakers, followed by a stint at the Brisbane Strikers. Both stints were largely unsuccessful, his sides reaching the finals only once.
In 2003 he became the inaugural coach of Adelaide United. Kosmina coached United to an impressive 3rd in the final season of the NSL. Maintaining his job for the inaugural season of the Hyundai A-League, Kosmina led his side to the Minor Premiership but a poor finals series saw them finish 3rd overall. The next season saw mixed results for Kosmina and Adelaide United.
Finishing 2nd on the table behind Melbourne Victory, Adelaide managed to reach the grand final, only to be thrashed 6–0. Kosmina's criticism of the refereeing of that match, coupled with the devastating loss and a touchline ban earlier during the season for a scuffle with Victory captain Kevin Muscat, saw him forced to resign by the Adelaide board.
After the sacking of Branko Culina by the Sydney Football Club Board, Kosmina was confirmed on 24 October 2007 as the new Sydney FC coach. Since signing with Sydney FC Kosmina made an immediate impact; winning his first game with Sydney 3–2 against rivals Central Coast Mariners at the Sydney Football Stadium.
Sydney FC beat the LA Galaxy 5–3 at Sydney's Telstra Stadium in a friendly, and also won a thrilling 5–4 victory against the Central Coast Mariners at Bluetongue Stadium. Following Sydney FC's poor run in the 2008/2009 season (missing the finals for the first time), John Kosmina had his contract terminated in late January 2009.
He was announced the manager of the Adelaide Raiders, a semi-professional club playing in the FFSA Super League. On 1 September 2011, it was announced he had signed as senior coach of FFSA Super League club Croydon Kings after more than 35 years away from the club. It was announced on 18 December 2011 that Croydon Kings had agreed to released Kosmina from his coaching contract so he could accept the Adelaide United manager position.
Return to Adelaide United
On 18 December 2011 he signed as caretaker coach with Adelaide United for the remainder of the 2011–12 A-League season. On 22 March 2012 it was announced he had signed a one-year contract with the club to stay on for the 2012–13 A-League season. On 28 January 2013 he stood down as manager of Adelaide United, citing a lack of trust at the club.
He has been appointed Senior Coach and football leader of the Brisbane City club on a 3-year contract for the 2016 season and beyond, and expected to start training with the team after the conclusion of the 2015 season. 
He occasionally appears on Fox Sports as a commentator and football analyst. Kosmina co-hosts a weekly Internet television show about football on Australia Live TV with Ross Aloisi, Two Up Front and the episodes are on AustraliaLiveTV.com.
