Croatia coach Slaven Bilic has concerns over his Tottenham players Luka Modric and Vedran Corluka.
"I am worried about the results at Tottenham, where some of our key players are playing - defender Vedran Corluka and in particular Luka Modric," he said.
"Luka is aware the situation is not good. He is aware that more is expected of him and that he has to lead the others.
"One of the things we must do at team headquarters is help set him on the right road."
