Stoke boss Tony Pulis feels Chelsea must be patient with interim boss Rafael Benitez who has had a mixed time of it so far since taking over from the sacked Roberto Di Matteo in November.
Pulis, who Potters side meet Chelsea on Saturday, emphasised how important it is for managers to be given a decent chance to prove themselves at a club.
Regarding the animosity towards Benitez, Pulis said: "I had it here when I came back after the spell away.
"You have to grind it out and get through it. You have to get results and that is what Rafa will have to do.
"If he gets results and he gets lucky, then he has a fantastic football club to build. He has proved before at football clubs that he can manage at the highest level.
"Given the chance, who is to say he couldn't do it at Chelsea? But he needs the opportunity, and that does not mean weeks or months - you have got to give people time."
