Clark admitted he felt nothing but pride for his keeper in a match which turned into a brawl after England's black players were racially taunted.
Clark, whose side face Leicester tomorrow, said: "Jack handled himself impeccably and was a credit to the club.
"Of course it will help him grow as a man.
"I had a similar experience myself years ago when I played for the Under-21s in Turkey.
"We've got a potentially top-class keeper on our hands. I hope the limelight stays on him."
