Clarke was impressed by the on-loan Dynamo Kiev left-backâ€™s introduction to English football.
â€śI thought Goran Popov came in on his debut to play in a game like that and showed the qualities heâ€™s got,â€ť he told the WBA website.
â€śWe had no doubts he would be able to handle the game.
â€śHeâ€™s an experienced player, has played in a lot of big matches, and he showed that today.
â€śHeâ€™s got a terrific left foot, knows the game, knows how to defend, and is a strong boy.
â€śHe gives us another good option in the squad.â€ť
