Borussia Dortmund manager Jurgen Klopp has leapt to the defence of tonight's opponent Arsene Wenger, by claiming the Arsenal boss has done the best work of any Premier League manager in the transfer window.
Wenger is currently under fire for leaving the Gunners threadbare in defence ahead of their Champions League opener, with just three recognised defenders fully fit and quite possibly rookie full-back Hector Bellerin facing a baptism of fire to say the very least.
Klopp excited by Arsenal's dynamism
Klopp has quite the opposite view on Wenger's £83.8m outlay though, insisting that Danny Welbeck, Alexis Sanchez and co. all fit Arsenal's style perfectly and will be a big hit at the Emirates if given time.
The maverick Dortmund chief told reporters at his pre-match press conference: "I think that Arsenal have done the best job with regard to transfers. What happened with England in the transfer window, even if it was last minute, yes Arsenal have done a good job.
"Now they'll simply be aiming for stability. This is a team which can play the kind of football Arsene Wenger always demands. Arsenal now have a serious defence which can cover spaces on both sides of the pitch because they have so much pace now.
Third-year showdown holds no surprises
Later tonight Klopp will get the chance to find how just how rapid Arsenal can be in the final third when he takes on Wenger for the sixth time in just three seasons, the two now familiar foes in Europe's premier club competition.
Dortmund come into the clash with an injury list which is more than comparable to Arsenal's, including captain Mats Hummels, Marco Reus and a whole host of midfield options, among them the still sidelined Ilkay Gundogan.
Both teams earned impressive victories away from home when the two teams squared off in the group stage last season, with Arsenal's famous victory at Westfalen earned courtesy of a header from Aaron Ramsey.
It will take something special to repeat that feat though, with Calum Chambers aiming to beat to tonsillitis and improve a patched-up defence which will no doubt be tested to the full once again this evening.
Klopp is seemingly in doubt that Wenger's thin squad are up to the task though, ahead of what promises to be intriguing Champions League showdown.
