"Insua has a lot of potential. He's only 17 and is still eligible for our youth team, yet he's already played for Argentina Under-20s. That tells you something about his quality," said the reserve team coach.
"To say it was his debut, I was very pleased. The potential is there and we now have to make sure we harness it.
"He is a prospect, we have a lot of prospects. You have to be exceptional to get into the Liverpool first team, but we have some very good players who are going in the right direction. Now, they've got to flourish over the next year to 18 months."
