This is a genuinely imbalanced Group E clash as Estonia are yet to open their account in the Euro 2008 qualifying rounds. Croatia are on top of Group E and will not worry overmuch about this game.

Estonia coach Jelle Goes had recalled Marek Lemsalu for the games against Russia and Israel in March because of a paucity of players. Now many of his injured and suspended players have returned so he can bank on Enar Jääger and Raio Piiroja. Andrei Stepanov also makes a comeback from injury.

Goes has also included defender Urmas Rooba, who was out of football for 15 months due to injury. Another notable presence in the Estonia squad is Erko Saviauk, who makes a return two years after he played his last international game.

Croatia coach Slaven Bilić is also plagued with injuries in his squad after defender Boris Živković pulled out following a recurring knee injury. Bilić has roped in NK Dinamo Zagreb defender Dino Drpić as a replacement and will be hoping to get through crucial matches against Estonia and Russia without further setbacks.

"Živković felt a problem with his knee," said Bilić. "He has had problems with it before and I cannot allow us to have another player recovering from injury so I have called up Dino Drpić."

Bilić is focused on the Estonia game although he admits the Russia match is the most crucial one. "I don't want to talk about Russia, first we have a match against Estonia," he said. "It is always difficult to play against Estonia. Even when I was playing we had a hard job to defeat them."
