Tommy Docherty is not a huge fan of Jose Mourinho, with the former Manchester United manager saying "if he were made of chocolate he would eat himself."
Mourinho has led United's revival and their best run of form since the Alex Ferguson era following Monday's 2-0 Premier League win at West Ham.
Goals from Juan Mata and Zlatan Ibrahimovic made it seven wins from as many matches for United across all competitions, and 13 games unbeaten in total - the club's longest unbeaten streak since March 2013.
But Docherty, who guided United to FA Cup glory in 1977 during his five-year spell in charge at Old Trafford, is not convinced by the Portuguese boss.
