Klopp lauded Emery as one of the best managers in the business, highlighting his tactical acumen and track record of success with Sevilla, and attempted a veiled dig at Arsenal in the same breath.
"He is one of the best we have in the business," said Klopp.
"Some clubs weren't ready to wait for it, but looking back, maybe these clubs would have made different decisions. I've known him for so long. He always had a clear idea. Won plenty of times with Sevilla.
"Really tricky with Villarreal. He always organises his team really well. The job he is doing is absolutely exceptional. We all know how difficult it is to qualify for the Champions League and that he will probably do that is absolutely exceptional."
