After Hector Bellerin fired through Asmir Begovic to open the scoring for the Gunners early in the second half, Callum Wilson and Jordon Ibe scored within five second-half minutes to turn the game on its head.
With Sunday's result, Arsenal have now gone four games without victory in all competitions. It was a tight game, not a lot in it but we showed the spirit and desire to come back from a losing position.
"But now we've got to keep the momentum going, we can't relax".
"Once you're 1-0 up you should create more chances".
And while Wenger wrestles with problems on the field, the off-the-pitch saga involving Sanchez is adding to his concerns, with the manager admitting that continuing uncertainty surrounding the striker's future was the reason he was omitted.
On Alexis Sanchez transfer rumour, Wenger said: "Half in half out, you never know this kind of situation during the transfer period". That's why I decided not to do it.
The 20-year-old Brazilian winger's future has come under the scanner this month and he has been heavily linked with a move to England, with Arsenal believed to be leading the chase.
Mesut Ozil was also missing for the Gunners after being ruled out with a swollen knee but Jack Wilshere started despite having limped out of the midweek League Cup draw at Chelsea with an ankle injury. "If it's me in charge or somebody else, you can only do what is best for the club". Iwobi slotted an excellent pass inside left-back Charlie Daniels, allowing Bellerin to advance on Begovic before beating the keeper with a powerful angled shot.
Petr Cech is one clean sheet away from 200 in the Premier League but surrendered the opportunity to hit that landmark today when he raced off his line but was beaten to Ryan Fraser's cross by the outstretched left foot of Wilson, who directed the ball into the vacant net on 70 minutes.
Four minutes later Howe's men were 2-1 up after Wilson fed Ibe in the box who shot past Cech to spark delirium among the home support.
