Croatia coach Igor Stimac has used his Facebook page to seek fans' advice on an ideal composition of his squad for the forthcoming 2014 World Cup qualifier against Wales.
"I am opening a discussion regarding Tuesday's match against Wales. What is your ideal team for that match? What system would you apply against Wales? 4-3-3? Bring it on!" Stimac wrote to fans on his official Facebook page on Sunday.
After defeating Macedonia 2-1 in Skopje on Friday, Croatia sits in second spot in their World Cup qualifying Group A behind Belgium, with both teams on seven points.
Wales, which scored a dramatic 2-1 win against Scotland at home, are currently fourth with three points. Group A also comprises Serbia.
Croatia host Wales in the eastern town of Osijek.
