[4] Halfway through the France World Cup in 1998, with Bulgaria having played two games (0–0 against Paraguay and a 0–1 loss to Nigeria), Zdravkov was ranked as the 2nd best goalkeeper in form.
Although he went on to concede 6 goals in Bulgaria's loss to Spain in the next game, Zdravkov was an exceptional performer at the World Cup.
