Redknapp says there is one major new signing QPR chairman Tony Fernandes needs to make as soon as the season ends.
He said: “What’s most important for this club is a new pitch — that one is not conducive to good football — it’s bobbly and bumpy.
“The first thing club needs to do in the summer is invest in a new pitch. It suits us when we play the likes of Spurs and Swansea.
“But it won’t suit the way I want to go next season.”
