Some of the stuff in this thread is hilarious. If I compare the current Liverpool with the ours when he took over 2008, the former look like world beaters. The difference is actually huge. Not like many on here had any interest in us before winning the title 2011 or even our CL campaign 2012/2013 to actually know this.
With the possible exception of Reus who was already fantastic in Gladbach, each and every world class or at least top class player was brought to this level under Klopp. He created this team from scratch. His biggest strength will probably always be his talent for player development and creating roles which maximise the impact of overall only decent players.
The central question with Klopp at Pool would be how much time he is given to actually craft a team to his liking. With us it took him two seasons, the best hope of rival fans would be that the officials have less patience.
