It's not that difficult, though. Rodgers had them on the verge of winning a title back in 2014. There's no guarantee Klopp will do it because he has an incredibly difficult task on his hands, but I don't think him being successful with Liverpool is necessarily any more difficult for him than doing it with Dortmund was. Certainly, he should be able to get them back into the top 4, and with the league's lack of quality among the top sides, going from top 4 to winning the title isn't as much of a jump as it once was. I mean, for all they've fallen, a couple more wins thus far and they'd almost be title contenders.
That was a complete freak of a season though. They had no European football, they got knocked out of the cups fairly early, they caught many teams off guard with the Klopp-like tactic, Suarez went from being a dangerous-but-not-
that-threatening wide forward to a world beater, Sturridge miraculously stayed fit for more than two weeks, Chelsea, City, United and Everton all had new managers, and then Spurs replaced theirs with a PE teacher partway through the season.
Bayern, and to a much lesser extent Leverkusen and Schalke, have been the only teams over the last decade or so to show any sort of consistency at the top of German football. It's not unusual at all for a 'new' team to find themselves within a sniff of the Bundesliga title, especially if Bayern aren't at their best. For all the talk of the Premier League being poor at the top, it's incredibly competitive and Liverpool are still some way off the mark. Two wins now means nothing in the grand scheme of things and I fully expect that we'll see Liverpool finishing somewhere between 5th and 7th, along with Leicester. Doing it at Liverpool is far more difficult than doing it at Dortmund because the fact of the matter is that the Premier League is a tougher league. There's a reason we've seen just 5 different winners in its 25 year history, and with the best will in the world, I can't see Leicester, Spurs, Everton or Liverpool changing that any time soon. In fact, 3 of the 5 winners only won it because of some seriously high financial backing.
