Well for a start Barcelona were not the finished article at all. They had stagnated under Rijkaard and Pep was promoted from the Barca B team after impressive results. Barcelona at the time of him coming in were under performing and had negative influences within the dressing room which Pep removed. Do your homework and he actually started off at Barca with not very good results, and some of the Barcelona fans wanted him gone. What he did do was stick to his ways and asked the team, those that he wanted, to trust in his methods.....eventually proving right.
Klopp has had more time than Pep both in the league and at his club, in order to get his ideas across. Klopp's results at that time when he first arrived were up and down.
It was never going to be an easy ride this season, far from it. As I have mentioned before, those first 10 games were a freak. A series of results that made some think he had walked in and would run away with it this year.
Let him get his team, because our team at the moment is far from it.
