Borussia Dortmund manager Jurgen Klopp says he’s been impressed by Arsenal this season and is predicting tight affairs as the two clubs get set to meet each other twice in the next few weeks.

The German has lauded the form of the likes of Wilshere and Ramsey and paid tribute to striker Olivier Giroud who he says is ‘one of the best’.

“Arsenal have kept their style despite the criticism,” he told a press conference today. “I feel their style has always been modern and now I feel it is working well. I’ve been impressed with Arsenal’s development and it will be two teams playing very well playing each other.

“One year ago I don’t think many thought Arsenal could play without Santi Cazorla, but now they have Ramsey and Wilshere on the wings and Giroud is one of the best strikers.”

Klopp also pointed to the signing of Mesut Ozil as the man who can drive Arsenal to a new level.

“This team missed a player and I think that could have been Mesut Özil. He’s technically perfect, fast and has developed a drive on goal. He is a very intelligent player and could play in any team.

“You don’t have to force him in training, it is all natural and that is why it was a great idea from Arsenal.”

As for the outcome, both sides will fancy their chances, the Dortmund manager thinks the difference could be minute.

“They will be two close games and I think small things will be decisive and we will have to be ready for these small things.”
