Liverpool reserves coach Rodolfo Borrell says Mike Marsh has made an excellent impact.
The former Reds midfielder is now in charge of the U18s.
Borrell told liverpoolfc.tv: "He has done a great job with the U16s. Everyone can see he deserves to go through to the U18s.
"He also has experience playing professionally. I do not need to give him any advice. We talk regularly and I think it is a good move to move him up. He has a great attitude during the training sessions. He has knowledge, experience and I think he will do well."
