Arsenal boss Wenger knows they can dent Man City title hopes
City could go into the game eight points behind leaders Manchester United.
Wenger said: "I feel it's a want-to-win game for us and must-win game for City.
"A draw for them will not be good enough at this stage of the season. In the last two seasons they have come here to play for a draw.
"But both teams will be looking for a win this time."
