Czech Republic boss Pavel Vrba has no doubt Tomas Rosicky will be fit enough to participate at Euro 2016 having named him in his preliminary 28-man squad.
The 35-year-old midfielder played just 19 minutes for Arsenal in the entire 2015-16 season, coming on as a substitute in the FA Cup victory over Burnley on January 30.
A muscular injury has sidelined Rosicky for much of this year, but he featured for the Under-21 side in April.
Despite his lack of game time, Vrba has faith the midfielder - soon to be a free agent with his Arsenal contract set to expire next month - can return to fitness in time for the European Championship in France.
"I was in England three weeks ago to see how Tomas was for myself. I went back satisfied, I saw that Tomas handed the whole match and had no break," said Vrba.
"Even now, after two days of being in the training camp, he handles everything without any relief. I see no reason why he should not be ready for the European Championship."
Petr Cech is the other star name in the Czech squad, while uncapped 20-year-old striker Patrik Schick is a surprise inclusion.
