Birmingham City boss Alex McLeish is demanding Olivier Kapo justify his big wages.
"Kapo has hardly played. He is a big earner and is a big player that we would like to see make a difference in these games," Eck told Setanta Sports.
"People like (Sebastian) Larsson who has come on in leaps and bounds, he is in the Swedish squad, and these are the types of player we would look to win this game for us."
