Chelsea have lined up Massimiliano Allegri to be their new manager amid doubts about Diego Simeone, Football Insider sources understand.

The Premier League champions have made contact through third parties about the potential availability of Allegri in the summer.

A Chelsea source has told Football Insider that the Juventus manager has indicated he is keen on a move to England in the summer.

Italian Allegri, 48, has begun to learn English as he prepares to make a move to the Premier League.

His reputation has soared after he won the second Serie A title of his coaching career last season and only a Champions League final defeat to all-conquering Barcelona prevented Juve from winning an historic treble.

Chelsea have cooled on the idea of appointing Atletico Madrid manager Simeone in the summer amid doubts about whether his personality and management style would be suited to the English game.

Allegri, who also won the Serie A title during his four-year spell at AC Milan, is regarded by Chelsea as a manager capable of taking over the reins from Guus Hiddink when his interim spell in charge ends at the end of the season.
