Liverpool striker Rickie Lambert has tipped teammate Raheem Sterling to have "an unbelievable season".
The 19-year-old winger scored nine goals last season, and his fine form was rewarded with a place in the England World Cup squad.
"I've been really impressed by Razza on this trip and if he keeps on progressing the way he has done over the past year or two he's going to have an unbelievable season," Lambert told the Liverpool Echo.
"I don't want to put pressure on him but I think he can handle anything that comes his way. He's a top lad as well.
"Nothing fazes him and that's full credit to the management. The manager has created an environment for the young kids to go and thrive and you can see the benefits of that."
Lambert signed from Southampton for around £4m earlier this summer.
