Liverpool boss Jurgen Klopp says Billy Koumetio will learn from their friendly win over Blackpool.
Klopp admits he wanted greater intensity from the French youngster in the opening exchanges.
He remarked, "We had some problems in the first half. [The opening goal] was a pressed ball against a very experienced player, who was stronger in that moment. Billy played super balls, super passes and was there. Our last line played [for the] first time together like this, it is completely fine, but we were just not high enough.
"There were many situations where I though it must be offside, but it wasn't offside. For one reason at least, it was not offside because we were not really in line. All these things, little things to learn, but 17 years old, the whole life in front of him, which is really nice. [He is a] big talent and, as I said, he had a few really, really good situations, but in this press ball, it was not so nice."
