Manager Arsene Wenger was not a happy man after Aaron Ramsey's goal was ruled out for offside in Arsenal's goalless draw against Liverpool.
The Gunners struggled in the first half of the game and were grateful to goalkeeper Petr Cech who produced a number of phenomenal saves to deny Brendan Rodgers' men.
They dominated the second half as they went close in numerous occasions but in the end they had to settle for one point as the gap from leaders Manchester City increases to five points.
"We scored a regular goal that was disallowed, I don't believe I can do something about it," Wenger told BBC Sport.
"At the end of the day the referee cancelled out a regular goal. Like it or don't like it, it is a fact.
"We had chances but we couldn't finish them off. When you play at home and don't win, people always find problems.
"It is not the result or the complete performance but we came back in the second half.
"If you are not first, you play catch up, there are 19 times who play catch up."
