David Klemmer, James Maloney, Jake Friend and Jake Trbojevic have visited some sick kids at the Alder Hey Children's Hospital in Liverpool, England.

In the lead up to the four nations final between Australia and New Zealand, David Klemmer was joined by fellow Kangaroos teammates James Maloney, Jake Friend and Jake Trbojevic at the Alder Hey Children’s Hospital.

The four NRL stars spent time with the kids, the staff and their families.

“To come in here and cheer them up has been pretty cool,” Klemmer said.

“To make them laugh and see them so happy makes you feel good inside, especially when some of the kids are around the same age as my children.”

Klemmer and his teammates will continue preparations over the next few days ahead of the final at Anfield, Liverpool.
