Urawa Reds manager Gert Engels is wary of culture shock as his side prepares to defend its Asian Champions League crown against Al Qadsia in Kuwait on Wednesday.
Urawa received a bye into the quarterfinals by virtue of winning the title last season, but Engels insists the lack of match practice against continental teams this year could put his side at a disadvantage.
"It is really important because it is our first game against a team from another country," he said.
