However, Cunningham told Sky Sports News: "We have got Luke Walsh, Travis Burns and Jon Wilkin who can play seven and I've got great juniors coming through. I am quite comfortable in the half-back department.
"Theo is a super kid, a great player and he has a very big future. He is a very talented kid and I am sure there will be a lot of interest in him.
"But maybe the Saints thing is a bit of smokescreen for somewhere else because I am very comfortable in the halves."
Fages has scored three tries in 13 appearances in the Super League so far this season.
