The Spain midfielder and his Barcelona team-mates Xavi and Cesc Fabregas have lamented the quality of the playing surface in Gdansk after their Euro 2012 opener
The pre-tournament favourites fell behind to Cesare Prandelli's men on the slow playing surface but rescued a point thanks to a Cesc Fabregas equaliser.
And, after the match, the Spaniard hit out at the quality of the pitch, claiming it stifled Vicente del Bosque's team's passing football.
He told reporters: "Seeing the pitch in those conditions is a disaster. It was incredibly dry and that makes circulation of the ball difficult."
Iniesta's Barcelona team-mate Fabregas was also quick to comment on the conditions after his side's Group C opener.
"I can't complain, but we deserved much more." he said. "It's shameful that we still have to play on pitches like that."
And Xavi added: "The fact that they didn't water the pitch persecuted our dynamic and fluid play."
Barcelona captain Carles Puyol, who is absent from the tournament in Poland & Ukraine through injury, also later tweeted in agreement with his colleagues.
He said "For me, the best game we saw so far, and if they water the pitch, we'd see better football. I believe in La Roja!! Star Iniesta."
