Helm continued the positive impression he has given since joining the Clarets at the start of the month with another impressive performance in Burnley's 2-1 defeat at Lancaster City.
“There are some very good technical players in there and it's our job to give them that game management and that bit of savvy and work out the problems that are happening on the pitch," said the acting U23s' boss Michael Jackson to the club's website.
“Young Mark, who has just joined us, is an outstanding talent.
“He's still got a long, long way to go but you can the technical ability he's got.
“There were some pleasing performances in it and some where you think they need to do more.
“But that's where we're at. It's development but you want them to keep improving and they need to try and keep improving and learning from what's happened in the last game.
“That's our job to remind them and keep them on the right track."
