We played a wonderful first half. It was clear it would be a very intense game, you could see it already with the line-up of Arsenal; OK, Mesut Ozil was not in, [Alexis] Sanchez was not in, but pretty much the rest. "It was clear we needed to have an eye on the counter attacks and all that stuff. Both teams tried to play high pressure – that was the reason for a lot of long balls, which made sense. But after winning the second ball, both teams tried to play football. Especially in the first half, we did better. We played really good, created wonderful chances and scored only two times, and could have scored more in the first half." said Klopp on the Reds website.On whether he was surprised by Alexis Sanchez being on the bench, the former Borussia Dortmund manager added: "I’m 17 years a manager and I’m really not surprised about any line-ups in my life. Only if somebody broke their leg last week and then he starts. "Then I’d think I’d want to meet the doctor! We always make the analysis without knowing who is playing. You can imagine, we did it with Alexis Sanchez in the line-up, but then when [Olivier] Giroud is on the pitch, it’s a different game because they cross more often.

If he starts, then we could have already a better solution from the beginning." the German coach addedThe Gunners manager Wenger brought on his top scorer at half-time, with his side 2-0 down, and he provided the pass for Danny Welbeck's goal.
