Davies said: “I do not think he is worth £50,000 at the moment, to be honest, he has got a lot of work to do.
“He has got to find consistency in his game, because inconsistency can be his downfall at the moment.
“He can play in a number of positions and we are still wondering which is his best one.
“For now, he has just got to continue his education in the game.”
