Redknapp brings his Queens Park Rangers to the Boleyn on Sunday for what he admits is a very difficult game.
He said: “They look a good team with lots of pace and movement – it will be a big test for us.”
And in his morning press conference at Loftus Road he added: “I don’t know if it’s [the boardroom warning] made the difference for West Ham.
“They’ve brought some good players in, a couple of players with pace, they bought [Alex] Song in.
They’ve improved their squad basically, that’s the difference this year. I think they are a stronger squad.
“He’s got better players. They’ve got a good manager. That’s the difference really.”
