Liverpool boss Brendan Rodgers is ready to withdraw Raheem Sterling from frontline duty.
Sterling featured for the U21s in defeat to Manchester United this week.
"This is a kid weâ€™re talking about, so we have to take a wee step back," Rodgers said.
"What heâ€™s done since he stepped on to the pitch against Bayer Leverkusen in a friendly â€” I dare you to look around Europe and tell me a 17-year-old who has made an impact in one of the big leagues.
"There arenâ€™t many. It is so mentally and physically draining this league, it hurts experienced professionals and this boy has just stepped up from the Academy and played football and earned a contract.
"We have to nurture that and at times heâ€™s got to have a mentality to keep learning.
"What youâ€™re seeing now is more tiredness of the legs when before he could go up to people and take them on. That zip has gone and thatâ€™s down to fatigue. He will have experienced that before, but not in the limelight. Heâ€™s made such an impact that everyone is looking at him now, of course. Heâ€™s started his career at first-team level way before many get the opportunity."
