Arsenal's 19-game unbeaten run in all competitions came to a frustrating end on Wednesday night.
Against Southampton at home in the EFL Cup, where Arsene Wenger fielded a second-string team, the Gunners were poor and outclassed by a stronger side.
Jordan Clasie opened the scoring with 13 minutes played, the Dutch midfielder firing past Emiliano Martinez when the ball fell to him inside the 18-yard box.

Ryan Bertrand then doubled Southampton's lead 25 minutes later, pouncing on some woeful Arsenal defending and finding the bottom-right corner.
Fans at the Emirates Stadium voiced their frustrations at the end of the game and appeared to blame one player for the defeat: Carl Jenkinson.

The 25-year-old, filling in for the injured Hector Bellerin and Mathieu Debuchy, produced a diabolical display against Southampton and was arguably at fault for both goals.
He was nowhere to be seen when left-back Bertrand crossed for the first goal and gave away possession cheaply not once, but twice, for the second.
It was Jenkinson's double error in the build-up to Bertrand's strike that summed up his performance.
In the video below, Jenkinson recieves the ball from Gabriel Paulista under pressure. He then has two options: pass back to the Brazilian or to Aaron Ramsey in the middle.
Instead, the Englishman holds up possession, dribbles back towards goal, misplaces a pass to Ramsey and then gives away the ball again when it rebounds back to his feet.
From there, Southampton break and eventually find the back of the net.
Talk about a lack of composure and decision making.
Wenger bemoaned defensive errors in his post-match press conference and explained how giving away two cheap goals killed Arsenal's chances of winning.
"I'm disappointed," he said, per the Guardian. "We had a disappointing performance, particularly in the first half. I think we were not good enough defensively and gave cheap goals away.
"It was better in the second, but it was one of those nights where you look like you could play two hours without scoring a goal. We didn"t have enough urgency in the first half and were weak in some departments. We paid for that.
"We were not incisive enough and they were sharper than us and fitter. If you give someone a handicap of two goals, against a Premier League side it's difficult.
"We had players out there who are used to top-level competition, but we didn'thave the right urgency."
