Although Redknapp is willing to accept part of the blame, he pointed to the club's policy of signing injury-prone duo Andy Johnson and Bobby Zamora as one of the reasons why his job has been made so difficult.
"We've ended up with a badly balanced squad," said Redknapp, who has been without Johnson and Zamora due to their respective knee and hip problems.
"I felt Bobby Zamora and Andy Johnson being injured took away the strikers and you can't win football matches if you don't score goals.
"We got Loic Remy in and then we got Bobby back and he got sent off. It's been a bit of a disaster in that respect."
