"I knew he was a good passer of the ball but he wasn't forcing my hand when it came to selection. It was developing into a difficult situation because it was only a short-term deal and I knew we needed to take a look at him in a game situation.
"That opportunity arose when Mark Hudson fell ill before the Wrexham game just before Christmas. So in he went and it was his chance to show us. He did very well in that first game, even better at Darlington on Boxing Day and then at Notts County last Saturday showed a side to his game that has been missing.
"To be fair, he's performed better in games than in training which, for me, is fantastic. He had done enough for us to want to keep him and we've agreed that he'll stay to the end of the season and review the situation again then.
"He can add other aspects to his game and, hopefully, he will get stronger and better. It's early days yet."
Ross is set to continue in the squad for Saturday's game against table toppers MK Dons, we'll have all the big build up on MillersMAD starting later today.
