Manchester United legend Andrei Kanchelskis believes Chelsea's decision to sack Jose Mourinho was too hasty.
Kanchelskis is adamant United must not follow the same path as the Blues and be too quick to part ways with current Red Devils manager Louis van Gaal, despite the club remaining winless in their last six matches.
The former Manchester City loanee also believes United's neighbours should be careful what they wish for regarding the potential exit of Manuel Pellegrini.
"[Van Gaal] needs to be given until the end of the season and then a decision should be made," Kanchelskis said.
"Chelsea have already made a stupid mistake in sacking Mourinho.
"Manchester City are also close to making the same mistake."
