There seem to be a UK-premium on managers too.
Furthermore, I think people have been manipulated/underestimated by the influence of Suarez in 2014 (in combination with poor competition/low standard in the PL back then). You see his fans keep mentioning it over and over.
Maybe his «success» when he came in at Leicester too. But people must remember, Leicester became instantly much better when he came in. That is not a testament to Rodgers coaching, but rather that Puel held them back.
Anyway, there is so many examples of his teams falling short and regressing under him. Should not be a debate at all.
So, Rodgers can do no good; it is all because everyone else was bad? Ridiculous.
Why didn't Suarez do that, beforehand, under other managers? Why did it suddenly happen in that season? Rodgers does deserve credit for recognising that Suarez should be the focal point of the team and built the attack around him. That is Suarez's best ever season in his football career. He also built the attack around him: Sterling into the first team, Sturridge signed, and Coutinho signed.
Leicester went on to win the FA Cup, which absolutely massive. The problem with Leicester winning the Premier League is now people will use it to undermine any success a manager has at Leicester. That was a one-off situation. Winning the FA Cup is enormous to a club like Leicester, and he has no doubt done a fantastic job with Leicester due to his own coaching skills.
He has overachieved with Leicester. It may be coming down, now, but there is only so long overachieving can be sustained. It will fail eventually.
