The German believes that Arsene Wenger's tactical prowess could see the Premier League outfit go the distance, providing they avoid Bayern Munich along the way.
"They are young, healthy and good technicians. They won a clever game tonight and could go to the final and win it, as long as they don't play against Bayern Munich," The Mirror quotes Klopp as saying.
"It was 50-50 wasn't it. But football is a game of results. They had their first attempt on goal in the 63rd minute and they scored.
"We had a lot of super moments, but we were not precise enough. We had 11 shots before they scored and sometimes it was like they were defending with four legs."
A second-half header from Aaron Ramsey was enough to give Arsenal maximum points in Germany.
