History against Hungary and the Czech Republic
CZECH REPUBLIC
Vladimir Darida
The Hertha Berlin midfielder, who's teammates with Mathew Leckie, was recently named 2017 Czech Republic footballer of the year, finishing ahead of national legend goalkeeper Petr Cech in the voting.
A regular in the national team since 2013, the combative Darida has played 48 matches for his country, scoring four goals.
Tomas Kalas
The imposing centre-back inked a new four-year deal with defending Premier League champions Chelsea last year, where he has spent seven years, but played just two first-team games.
The 24-year-old has spent this season (as well as 2016/17) on loan at Championship club Fulham, playing a massive part in their drive to return to the English top flight.
Michael Krmencik
The 25-year old recently caught the eye of Newcastle United boss Rafa Benitez who tried unsuccessfully to bring the striker to Tyneside during the January transfer window.
Instead, he has stayed at Viktoria Plzen where he has scored 12 times in 18 league matches this season, as well as netting four goals in the national side's unsuccessful World Cup qualifying campaign.
HUNGARY
Balazs Dzsudzsak
In a 12-year professional career, the current national captain has played for PSV Eindhoven, Dynamo Moscow and Bursaspor before a move to the UAE club Al Wahda two years ago.
He has appeared over 90 times for the Hungarian national side and was a standout at Euro 2016 where his side defied expectations to top a tough group that included Portugal, Austria, and Iceland.
Ádám Szalai
A member of the national side since 2009, the 30-year old striker is approaching fifty caps for his country.
He has played the majority of his professional career in Germany where he currently plays for Hoffenheim, scoring three goals in 13 league appearances so far this season.
Tamas Kadar
The Ukraine-based defender spent four years on the books of Newcastle United and was recently the target of his former manager Alan Pardew who wanted to bring him to struggling West Bromwich Albion.
The 28-year-old defender has been a national team regular since 2011.
