Kashima Antlers manager Oswaldo Oliveira has registered his interest in signing want-away Kawasaki Frontale striker Hulk, but insists his priority is strengthening other areas of the team first. Hulk was transfer-listed by Frontale last week after repeatedly demanding to leave the club, just two league games after returning from a two-year loan stint in the J. League's second division. Kashima, which has hit 25 goals in six matches this year, is not in desperate need of a new striker, but Oliveira is keeping tabs on the 22-year-old's situation nonetheless. "We have one more place for a foreign player, and we can think about deciding in the near future," Oliveira said after Kashima's 2-1 win over Yokohama F. Marinos on Sunday. "Because of the league rules, he can't play until after the summer if we sign him. I saw him play in many games last year and he is an interesting player. But we have to think about the other positions first."
