Arsenal manager Arsene Wenger was delighted after reaching the Last 16 of the Champions League.
The Gunners produced a brilliant display of football to dispose of Borussia Dortmund and can still qualify as group winners in the unlikely scenario of a win away at Galatasaray and a home defeat for Borussia Dortmund against Anderlecht.
"We had a good start and overall it was a very intense game between two very good teams where you had to fight for every ball and be focused," Wenger said.
"I felt we had a good combination between our usual passing game and our transition from defence to attack. We were highly focused to defend well together from the first to the last minute and we always looked dangerous. Defensively we were very good as well.
"We were more under pressure because on Saturday we played well but maybe we were victims of our generous attitude going forward. Here we had a bit more urgency to defend, especially when we were 1-0 up.
"The injury situation is a problem because we have many games and we lost two players tonight.
"The first one is Mikel Arteta who has another calf problem and that looks quite serious. We also lost Yaya Sanogo to a hamstring problem.
"I think he [Sanogo] played well.
I decided tonight to got a bit longer from the start and he protected the ball well and won many challenges. He's a young boy but he he has presence, character and he's naturally committed.
"He has a natural, aggressive attitude up front that is vital and very important."
