Arsenal avoided a major scared as they came from behind to get their Europa League campaign up and running with a victory over Rapid Wien. However, goalkeeper Bernd Leno came under major fire for an error just after half-time.
Leno attempted to play the ball out from the box when he was caught in possession, allowing Taxiarchis Fountas to slot home.
Pierre-Emerick Aubameyang came off the bench to score the winner after David Luiz had headed the Gunners level.
However, former Arsenal defender Martin Keown feels Arteta may have made a mistake in letting shot-stopper Emiliano Martinez join Aston Villa for £20million.
The north Londoners were trying to raise much-needed funds and opted to let their No 2 move to Villa Park.
“Having let Martinez go, who was magnificent, so to see Leno making these types of mistakes, you wonder whether it was the right call,” Keown told BT Sport.
“It was a difficult night for Leno. The team had their backs to the wall but showed very good character to get back into it. A couple of changes were made.
“I thought when they changed it actually and went back to a five, the pictures then became more familiar to the players and they found a way to win this match.”
Meanwhile, fellow pundit Owen Hargreaves hailed Arteta for bringing on club captain Aubameyang to make the difference.
“Great ball in from Pepe, it really was,” he added.
“It’s part of our game,” the Spaniard said of playing it out from the back. “We need to understand when we can do that and when we should kick the ball into the stands.
“They will understand better and better the type of balls we have to play in those areas and to who in relation to the pressure that’s coming.”
