SEAN O'Driscoll has urged Nottingham Forest to consider fitting under-soil heating at their training ground.
The facilities at the Nigel Doughty Academy are already some of the best outside of the Premier League.
But the club's owners, the Al Hasawi family, have already stated they plan to further improve them in the future.
And, with the cold weather having closed in for the first time in the past week, O'Driscoll believes having under-soil heating could give Forest a further advantage over their rivals.
The Reds have managed to train this week, despite freezing temperatures on Wilford Lane – although they did have to train later in the day, when the pitches had thawed out slightly.
And O'Driscoll said: "We have to look at it, with the weather being harsh every winter.
"If you are a Premier League side, you have one area on your training ground that has under-soil heating.
"That might be an investment the club should look at. It might give you an edge over sides who cannot train and have to go indoors.
"We have been OK, we just moved training back a little bit.
"It is not ideal, but it is winter after all . . ."
