Arsene Wenger has reserved special praise for Borussia Dortmund ahead of Tuesday's Champions League tie at the Emirates stadium.
Arsenal face the Bundesliga side in a repeat of the tie two season's ago, which saw the Gunners run out 2-1 winners but Wenger insists this team is much better than the one he faced in 2011.
He told Arsenal.com: “When we played them two seasons ago in the Champions League they were short of experience. They reached the final last year so they have certainly more confidence than before."
Dortmund lost to Bayern Munich in the Champions League final last season. However, on route they displayed an exciting brand of football that earned wide praise throughout Europe.
More impressively, the team has been built on a small budget and Wenger has praised manager Jurgen Klopp for using a similar style to Arsenal's in building his successful side.
“Klopp has done extremely well and given a new lease of life to Dortmund,” said the manager. “Overall, you can only congratulate him for the quality of the job he has done, it is exceptional.
“They have created a style with plenty of players who have been bought in. But they bought with very intelligent scouting.
“They have done it in a little bit different way [to us] but, as well, not in the most expensive way and they deserve credit.
“I feel sympathy for them too of course because they lost big players, like Mario Gotze, at a very young age. We have gone through that. It hurts.
Although they lost the young Gotze to their arch-rivals Bayern Munich, Wenger insists that it hasn't affected the quality of the side or the style of their play.
"Yes they lost Goetze, but they got Marco Reus, so the structure and quality of the team is similar as before. It's still based on Polish quality.”
