McDonald, 17, has been a rock at the heart of the U18's defence this season and is tipped for the very top by the Potters management, who have taken the step of loaning him out whilst he is still in the youth side, usually a sign of the promise being shown by the player.
City U18 lie 4th in the league, and have only been beaten once all season, as Ady Pennock looks to get the players ready and able to be given professional contracts next summer.
