I agree with all of that, I am not disputing his ability as a manager, nor am I saying that he's a fraud, but he took a treble winning side, that was expected to be get to another European cup final as they were at the peak of their powers [whether that's the right expectation or not].
Doesn't change the fact that he broke records in the league that none of his predecessors could over the years. It clearly is a pre-cursor to what he's doing now in the Premier League.
I don't look at his time at Bayern to gauge his ability as a manager, he had no proper competition there, and he's great at maximizing top players. What he did at Barca was far more impressive and more telling of how good of a manager he is.
Again, he was one of the best ever Bayern had in terms of League results. He didn't just 'win' leagues. He blew the league away like no one else had done before.
I don't disagree with the last part. He did much more at Barca, but his Bayern stint doesn't make him any less greater.
Getting knocked out by Monaco and Spurs imo is inexcusable however.
Not any more inexcusable than Ferguson getting knocked out by Monaco, or in group stages led by mighty IFK Göteborg, again in Group stages to Villareal, Benfica & Lille or once again in Group stages to Benfica, Basel & Oțelul Galați.
Or Mourinho getting knocked out by Sevilla. Or the fact that Mourinho never won the CL with both Chelsea and Real Madrid. Failures?
This competition is tough. If you come to think of it, only Zidane has a perfect record in the CL and even he has a question mark on him, because it wasn't even the squad that Zidane built in the first place that was good enough to win the CL. The squad was already there & it wasn't Zidane's.
