Everton have parted company with the former England manager. And it appears Silva is their prime choice to take his position.
But Cottee is not convinced at what he saw of Silva at Hull and Watford.
He told Sky Sports News' Premier League Daily programme: "You'd like to think they've been thinking about who to appoint.
"I'm not so sure whether he's the right man to take the club forward. Everyone said he did a good job at Hull but ultimately they did get relegated and then after a pretty good start at Watford he then got the sack, albeit down to Everton's interest.
"I wouldn't be surprised if he turns up but I'm not quite sure he's the right man for the club."
