Kean, 23, moved to Everton for £27.5million in 2019 to play under Silva, but his time on Merseyside was not what the striker hoped for.
But after reported interest in Kean from Fulham, Silva has confirmed he is not seeking to re-sign the Italian, who Juventus have put up for sale.
“No, Moise Kean is not a solution for us”, Silva said. “I don’t like to talk about players that are not our players. Moise Kean is a player from Juventus. But I can confirm he is not the player we are looking for.”
Asked about Mitrovic, Silva said: “I will not answer about Mitrovic because it would be a lack of respect to the players we have in our squad right now. He understood my ideas and executed that.
“With more time it would be less difficult”, Silva said about replacing the Serbian international. “Right now, at this moment in the mark, it is really difficult. This is the problem when you leave things for the last week of the market.
“We are not in the best position.”
