The Gunners suffered big away defeats at Manchester City, Chelsea and Liverpool, but Wenger says that failing to beat Aston Villa, Everton and Swansea City at home was equally damaging.
"The restriction we had was when we only made draws and not wins, that is where the missing points are at the moment because we are very close to the top," Wenger told reporters.
"Maybe one or two wins at home would have made that difference.
"The regret we have is that we have been remarkably consistent but against some teams who did not fight for the Premier League title we could not claim the points."
Arsenal face West Bromwich Albion on Sunday.
