Pep Guardiola was left to rue Manchester City 's lack of cutting edge and the Selhurst Park pitch as they drew 0-0 with Crystal Palace to hand Liverpool a boost in the Premier League title race.
The Citizens racked up 18 shots on Monday but were unable to breach Patrick Vieira 's side despite a gluttony of guilt-edge chances.
With his players unable to put the ball in the back of the net on grass that was "not perfect," Guardiola vented post-match, with Jurgen Klopp 's men now just four points behind them with one game in hand.
