Former Celtic star Tom Boyd says the club must demand top price for Victor Wanyama.
Southampton are planning a £10 million bid for the Kenya international.
But Boyd told the Scottish Sun: “I don’t think £10m would be enough for Victor Wanyama. I’d certainly be hoping for a lot more than that.
“Victor and Gary Hooper are the two I’d like to see stay, but Gary’s different in that he’s coming into the last year of his contract and there’s a risk he’ll leave for nothing at the end of that.
“Wanyama still has two years left on his contract. Neil Lennon said he wanted £25m for him and I’d go along with that. Why not? If the bidding is to start at £10m then there’s a lot of room for it to go up.”
