Cardiff target Wanyama admits turning down Southampton
Celtic have already accepted a bid for the Kenyan international, but the midfielder has rejected Saints' first proposal to him.
Wanyama said: "While the bid was ok for Celtic, the terms were not right for myself and my agent.
"I am open to what offers are made, but I am relaxed and it's important that Celtic are happy too."
Cardiff are said to have made their own counter proposal in a bid to persuade Wanyama to join them.
