Numan told the Daily Record: "If he gets the chance Virgil should go to England in January or at the end of the season. Over the last two seasons he has proved he is too good for Scottish football.
"If you are linked with some clubs in England it's natural you are going to want to move away because you have Celtic in the top league here and who else?
"When a player comes to Scotland you spend a year or two trying to impress.
"But when you're there four years and play Ross County seven times a season it can be hard to motivate yourself. You can stay too long."
