Novak Djokovic criticised the surface after needing three sets to win his first match on the blue clay at the Madrid Open.
The world No1 beat Spain’s Daniel Gimeno‑Traver 6-2, 2‑6, 6-3 but claimed centre court was in a different condition to the practice courts.
“To me that’s not tennis,” said the Serb.
“Either I come out with football shoes or I invite Chuck Norris to advise me how to play on this court.”
