West Brom boss Tony Pulis believes it would be disrespectful to Jose Mourinho and “utterly out of order” to credit Guus Hiddink with Chelsea’s revival.
The Baggies to go Stamford Bridge on Wednesday with the champions unbeaten since Mourinho was sacked last month.
Hiddink has taken charge for four matches but the Blues are three points behind Albion in the Barclays Premier League.
The Dutchman replaced Mourinho as interim boss until the end of the season and has won two and draw two of his games, with Chelsea 14th in the table.
But Pulis rounded on any of Mourinho’s critics who would suggest Hiddink is the sole reason for Chelsea’s return to form.
He said: “The fact is Mourinho won the league last season by a country mile. There might have been other reasons that things didn’t go so well this year but to put Jose down is completely and utterly out of order.
“What you said was disrespectful to Mourinho and also the players that won the league last year because they played some great football last year, some fantastic football.
“We’re in for a tough game It’s Chelsea they’ve some wonderful players and we’ll have to be on it and at our best.
“That’s the same with every top four or five club. If you go away and play against them you have to have at least ten of your players playing to their maximum to get a result.”
