The two 18-year-olds played for Adam Sadler's reserves on Wednesday against Newcastle Blue Star.
"The lads have only been in the country for a day, but the way they have gone about their business is great," Sadler told the Evening Chronicle.
"I think they performed well last night.
"It's difficult to go to any country and get straight into it with lads that you don't know in tough conditions. They coped well."
