West Ham midfielder Tomas Soucek scored a hat-trick as the Czech Republic came from behind to thrash Estonia in their opening World Cup qualifier in Poland.
Soucek scored twice before the break and tapped the ball into an empty net to make it 5-1 after 48 minutes.
Jakub Jankto scored a sixth before Henri Anier netted for Estonia.
It almost doubled Soucek's international tally, with four goals in his previous 29 Czech Republic games.
The 26-year-old has scored nine goals in 32 West Ham appearances this season.
