The highly-rated Czech Republic defender - capped 17 times by his country at Under-21 level - joined the Blues from Slavia Prague in January on loan for the rest of the season.
He's gone from a regular title-challenging team to being plunged into a relegation scrap at St Andrews but appears to have coped well in his six matches so far.
"We played together at Slavia Prague," said Radek, who took the same loan path to us in January 2005 having spent all his career at Slavia.
"Martin is young, strong, talented and has played Under-21 for the Czech Republic - and he's a big talent for the Czech Republic in the future.
"It is very different from the Czech Republic to playing in the Premiership.
"It's not easy because it's a new squad, a new mentality, a new country and he is playing in a high pressure situation at Birmingham.
"I remember at Slavia Prague we were usually at the top of the league fighting for the title and that's pressure, but nice pressure. This is a different type of pressure but it's a good chance to show what he can do.
"I watched his first two or three games and it's very hard for him but he's playing and I think he'll do well. I think he's a good player for the future."
Radek Cerny sees Martin Latka as one for the future - and believes his present situation at Birmingham will bring his former teammate on even further.
