Leicester finished last season 14th having been promoted the previous season.Has a team scraped relegation one year then with almost the same squad won the league the next year?Again I doubt it.
When we won the title under Mercer and Allison we finished the previous season 15th having been promoted the season before.
At one point Mourinho looked like he was going to manage the opposite feat this season until he was sacked sudden changes in forums happen.
