Hyundai A-League Champions Sydney FC completed the signing of Polish international winger Adrian Mierzejewski on a three year deal in August 2017.
He was the Polish League (Ekstraklasa) Player Of The Year in 2010 beating current Bayern Munich star Robert Lewandowski to the top award, while his combined career transfer fees total over $12 million.
His transfer to Trabzonspor in 2011 reportedly produced a record fee ($7.82m) for a Polish League player which stood until English Premier League club Southampton purchased Jan Bednarek last month.
A season later he was a member of the Poland national team which took part in the Euro 2012 Championships in his home country.
The 40-capped midfielder brings extensive experience to the Sky Blues, having played in the UEFA Champions League and UEFA Europa League for Turkish side Trabzonspor, as well as in the AFC Champions League for Saudi Arabian club Al-Nassr.
