Wenger admits anything other than a maximum-points haul will do either side's ambitions little good.
"I think they are in a situation where a draw will not be good enough, and we are in the same situation," said the Arsenal manager.
"The fact that both teams have to absolutely go for a win promises a more open game.
"When you are in that (title) situation, you don't want to drop more points because it can be damaging for your chances."
Wenger added: "It (the championship) is still very open. When you watch the games, no team today goes into a Premier League game and is sure to win it, therefore I believe every team can drop points.
"It is much more open than people think it is."
