Kashima Antlers cannot afford any lapses or will pay the price against African champion Mamelodi Sundowns in their Club World Cup quarterfinal match, manager Masatada Ishii said Saturday.
The J. League champion reached Sunday's last eight at Suita Stadium with a 2-1 win over Oceania champion Auckland City of New Zealand in the opening match in Yokohama on Thursday.
Kashima, though, had to claw its way back for the victory after falling asleep and conceding from the set piece early in the second half.
