Promising midfielder Paul Okon-Engstler is headed to Germany, the first of an emerging batch of Socceroos to move to bigger leagues.
The 21-year-old, who impressed in Australia's World Cup campaign, is joining Bundesliga club FC Koln from Sydney FC.
Okon-Engstler's transfer is reportedly set at one million Euros ($A1.6m) for the Sky Blues, who signed him on a three-year deal in July last year.
