COPENHAGEN (Reuters) - Croatia must quickly get over the news of winger Ivan Perisic's positive test for COVID-19 and, with plenty of replacements on hand, focus on Monday's Euro 2020 round-of-16 clash with Spain, coach Zlatko Dalic said. Perisic, who drove Croatia's effort in the group stage and scored in their 1-1 draw with the Czech Republic and 3-1 win over Scotland, is in self-isolation after testing positive on Saturday but Dalic refused to complain. "Perisic is hard to replace and he's been our key player in the group stage but this can happen and we have to adapt," the 54-year-old coach told a news conference on Sunday. It's going to be tough but I am confident that we have it in us to beat them." "They have a top-quality midfield but so do we and we'll have to be compact all the way in order to stand our ground."
