French club Paris St. Germain, German outfit FC Cologne and Sheffield United are all keeping tabs on 25 year old Midfielder Geraerts as his Standard Liege contract expires this summer.
Geraerts said: "Belgium is indeed my preference, but if a foreign club really wants me I am prepared to make that step.
"But I don't want to speak about foreign clubs. It's best that I keep my lips sealed about that."
