Former Manchester United manager Tommy Docherty says if current boss Jose Mourinho "was made of chocolate he would eat himself".
Docherty has not been overly impressed by the Portuguese's performance at Old Trafford and does not think he will enjoy a long stay at the club.
Mourinho oversaw League Cup and Europa League success last season and his side are currently second in the Premier League.
But the former Chelsea and Real Madrid boss has been criticised for his side's style of play - particularly after last month's Champions League exit to Sevilla - and for his treatment of certain players.
