Foley played alongside Vitoria Guimaraes striker Balde at Cercle Bruges in 2011/12 and is of the belief that he can reach the same heights as ex-Germinal Beerschot man Wanyama has at Parkhead.
“I played against Wanyama when he was at Beerschot, before his move to Celtic,” he told SunSport.
“He was a good enough player who had potential.
“But he’s gone on to Celtic and done a lot better than I thought he would.
“He was pretty raw when he was there. But he’s reached a new level in Scotland and I think the same can be true of Amido.
“He was never a big star in Belgium, but neither was Wanyama and look what’s happened to him since.
“Amido must have improved a lot since we played together at Cercle Bruges. He was very raw when he was there, but in fairness he was a still a young man.
“The first thing you notice about him is that he’s a really big unit — he’s well over six feet tall.
“He’s a battering ram type of striker, so you can see him being well suited to British football.”
