Steve Cotterill has been appointed as the assistant manager at Birmingham City after the club brought in Harry Redknapp as their new boss.
"The players have put in the club in the position they're in - you can blame who you like, they've obviously not performed", said the ex-Portsmouth, West Ham and Tottenham boss.
Birmingham is three points above the League Championship relegation zone with three games remaining after a disappointing run of results under Zola.
A season that began promisingly under new Derby manager Gary Rowett, who took Birmingham into contention for promotion, turned into one of significant struggle when Rowett was succeeded by Zola.
"I will come and live up here until the end of the season", Redknapp told TalkSPORT on Tuesday. "Now I've got a slightly bigger problem".
"I could easily have said goodbye to it all but I love it".
"There are still nine points up for grabs and we have Leeds on Saturday".
Redknapp's last stint in management was in charge of Jordan in 2016, where he oversaw two World Cup qualifiers, beating Bangladesh 8-0 in the first before losing 5-1 to Australia.
The Italian led the team to just two wins in 24 matches in charge. I am sorry because I came to Birmingham with huge expectations.
He added: "I said to them "if you don't make the play-offs, I don't want any money".
"Results unfortunately haven't been good and I take full responsibility for that. If I can get them going and get a bit of belief back in and pick up a win or whatever we need to stay up, that's all I can do".
Redknapp's first game on Sunday will be at local rival Aston Villa. They then play Huddersfield before ending the season against fellow strugglers Bristol City.
