Earle wrote in The Sentinel: "I like this lad, and I don't think Celtic's £12m asking price is unreasonable.
"Wanyama is very much a modern Premier League midfielder. He's powerful and athletic while also being good on the ball. In fact, he is similar to Yaya Toure in style.
"He's only 21, but showed in big Champions League games for Celtic that he can handle top-class opposition.
"If Stoke were able to get him for £12m, I'd expect them to be able to sell him on at a profit to a Champions League club."
