Man United are said to be preparing a bid of around £25m for the Burnley defender, which is 10 times more than they sold him for in 2014.
Just as the Portuguese boss urged executive vice chairman Ed Woodward to break the world record for Paul Pogba last summer, he is set to re-sign Keane three years after he left Old Trafford.
The Man United hierarchy allegedly understand that Burnley have accepted the 24-year-old England international will move at the end of the campaign.
He is understood to have made it clear that he will not sign a new deal and Sean Dyche will accept a transfer as they look to cash in on his services.
With plenty of clubs expressing their interest in his signature such as Tottenham Hotspur, Liverpool and Everton, Burnley’s priority will be getting the best price possible for Keane.
He’d be solid at United but it’s just another player that we’ve let go only to sign further down the line for more money, after seeing him cheering in the crowd during United’s 2-0 win against Chelsea, it seems a deal could be encouraged.
