Have to say that what Klopp achieved with Liverpool in such a relatively short period of time is remarkable. He inherited what many would consider a pile of crap, and with a few key purchases converted Liverpool into an unstoppable force. Most notable additions were at the back: a keeper cost you a European final, so he fixed it by bringing in one of the best in the business. He sured up the back line with one of the greatest CBs the world has seen in a while. And brought up lightning quick wingbacks that supplied the ammo for a deadly front 3. But we can't forget Henderson who I think many people, Scousers included, had written off a long time ago. He was the glue for the whole team, as well as its engine.
It's for those reasons, and more, that I'm one of the Gooners who still wonders "what if we had gotten Klopp when we wanted him?" - well done, Liverpool. Now get that man a statue!
