Midfielder Radoslav Kovac has revealed he has retired from international football in order to concentrate on his club career with West Ham United.
The 30-year-old Czech Republic midfielder took part in the 2006 World Cup and 2008 European Championship, but has called time on his international career after winning 30 caps.
"I want to concentrate on the English league," confirmed Kovac, who joined the Hammers from Spartak Moscow on loan 12 months ago before signing a permanent deal last summer.
"Now at West Ham we have an ambitious project. It has been a long and beautiful experience.
"I've played at the World Cup and the European Championships, winning with the youth team.
"I'm over 30 so I decided to quit."
