The Hoops could be trailing Paul Lambert’s side by seven points should the Birmingham outfit come out on top at Villa Park – but Redknapp feels even defeat wouldn’t end of their hopes of beating the drop.
“It is a big game for both teams. We’re both in the relegation battle so it’s going to be really important and have a bearing on the league table,” said Redknapp.
He added: “It’s not necessarily [make or break] but it will certainly help. It would make a difference to how the league table looks on Sunday morning.”
And Redknapp feels that his side are not under as much pressure as their relegation rivals after coming from a seemingly unsalvageable position to the cusp of safety in recent weeks.
“They are a massive club with a young team. The pressure of the home crowd can affect performances,” he said.
“We go into the game away from home. People wrote us off a few weeks ago so we’re coming from a situation where we were no-hopers, but now we’re back in there with a shout.
“There’s no real pressure on us.”
