Klopp's approach has changed since that day, however, with the German navigating a busy winter schedule of 13 games in 45 days by routinely changing his starting lineup.
Oxlade-Chamberlain would join Liverpool four days after the game and Wenger concedes he made mistakes that day.
"We have to analyse that well, and as well you have to guess a little bit who will play". That's how it is. "It is unbelievable, but he was not asked for this too much I think in the past".
And he rapped: "The biggest improvement for Oxlade-Chamberlain is being involved in goalscoring situations". He's really fit, you could see it at Bournemouth, there was not one second where you thought he looked exhausted.
"If you watch Arsenal in the past, their two decisive players were Mesut Ozil and Alexis Sanchez". "Here, we put it on much more shoulders, and if he's on the pitch he needs to be involved in situations like this".
Klopp is anticipating a stern test in the capital, with Arsene Wenger's side - who will be without the injured Olivier Giroud - sitting only one point behind them in the Premier League.
"They played a lot of long balls to Giroud, but he can not play and that will change a few things".
"They are a complete football team, able to do everything". We went to different camps, the boys were together all the time.
Whether it's been the calamitous displays from Dejan Lovren, Albert Moreno's penchant for an error or the lack of pace Ragnar Klavan possesses, it seems their backline always lets them down. "We are a team with very offensive orientation but that doesn't mean you have to give space away".
