Manchester City eased into a 3-0 lead early in the second half and proceeded to kill the game, slowing the tempo and keeping possession while Arsenal's players seemed happy enough to avoid a real hammering. As such, many Gunners fans voted with their feet by leaving well before the final whistle.
Things could go from bad to worse for Wenger, though, as the Premier League leaders are Thursday's visitors to the Emirates.
dabblebet go 3/4 (1.75) that Guardiola's side record another victory, which would be their 24th in 28 top flight matches this term and a third against Arsenal since November. A home win is priced at 10/3 (4.33) with a draw available at 3/1 (4.0) with the online bookmaker.
A Manchester City win with over 2.5 goals in the game is a 5/4 (2.25) play and considering that the visitors are looking well on course to break Chelsea's record of 103 goals in a Premier League season, that could be a popular bet with punters.
Wenger can call on some extra firepower in the form of Henrikh Mkhitaryan but a Gabriel Jesus cameo at Wembley is likely to be a grave concern for a defence that has leaked in each of their previous nine Premier League games. The Brazil international is 7/2 (4.50) to break the deadlock and 17/20 (1.85) to score anytime.
It's 13/8 (2.63) that City score three or more goals at the Emirates while four or more is 4/1 (5.0). That's something that the champions-elect have achieved eight times already in the top flight this term.
