Marshall full of potential - Ronnie
Marshall played 22 times for the Millers last season, and signed a 2 year deal with the club in the summer after leaving Blackburn Rovers.
Speaking to the clubs official website - themillers.co.uk, Moore said; "Marcus earned his deal and there is no doubting that he is a quality player, He is still a little raw, he needs to improve but we are going to work hard with him and I am sure he will develop as a player."
"It is obvious that he has potential, Blackburn saw that in him but it didn't work out. It happens to a lot of Premier League kids but I am sure that if he can carry on the way he has started for us he can push his way back up the leagues."
"Marcus is versatile; he can play wide right, wide left or down the middle so he gives us options, He has great ability so we just need to get that consistency to his game now." Moore added.
