The Kenyan midfielder proved his usual bustling presence at the base of Spurs' midfield and despite a flare-up with Theo Walcott late in the first half, he avoided a booking.
"He was very lucky to stay on the pitch, of course," Wenger told his post-match press conference.
"A few fouls, the elbow on Walcott for example. We have to cope with that. The referee makes the decisions."
Kevin Wimmer's 42nd-minute own goal put Arsenal ahead at a chilly Emirates Stadium, but Harry Kane's penalty early in the second half earned Spurs a share of the spoils.
Kane's penalty was awarded after Mousa Dembele's run into the box was halted by Laurent Koscielny and Wenger felt the decision was "harsh".
"From where I sit, it looked harsh," said the Frenchman, whose side squandered a chance to supplant Chelsea at the league summit.
"It didn't look a deliberate foul or that he was dangerous to score. Even speaking to some referees, you can give it or not give it. As Arsenal manager, I wouldn't have given it!"
Despite his frustration over the penalty, Wenger accepted the result was "fair" and his opposite number Mauricio Pochettino agreed.
"It's difficult to say one team deserved it more than the other," said Pochettino, whose side remain three points below Arsenal in fifth place with the last unbeaten record in the division.
"A draw is maybe the fair result. It's been a very difficult game for us, but 11 games unbeaten in the Premier League, we need to be very pleased."
