The big Swede said: "It's difficult to play against so many defenders. It was the toughest opponent so far, we cannot do great in every game but we won."
On Pedro's winner, Ibrahimovic added: "It was a great goal. When he plays he does well, he is technically very good and gives us extra strength. He's doing very well.
"They are three very important points and now it's six consecutive victories."
