Ukraine's World Cup players complained Tuesday that frogs were disturbing the sleep of the squad at their lakeside hotel in Potsdam.

Central defender Vladislav Vashchyuk told the Sovetsky sports newspaper that frogs in the Templiner See lake were keeping the players awake at night ahead of their Group H opener against Spain Wednesday.

"We have agreed we will take fishing rods to hunt these frogs," said Vashchyuk.

Hartmut Pirl, manager of the hotel where the squad are staying, told Reuters he had not had any complaints.

"There are frogs that croak. This is a nature reserve," said Pirl.

"None of the players have complained. If there was a problem I would know about it."

The other teams in the group are Saudi Arabia and Tunisia.
