Mate, i honestly have no idea why you are nagative constantly about Pelligrini, look at his career, Managed Real Madrid (and achieved at the time their greatest ever points total in la liga and their record ever goals scored total) was only replaced as they wanted Mourinho otherwise unlike most madrid managers he wouldn't have been sacked - only lost the title due to barca having possibly their best ever team that season under Guardiola
Qualified for and then reached the semi finals of the CL with Villareal a small spanish team who came out of nowhere and entirely with a team he built from the ground
Qualified and reached the QF with Malaga - another small spanish team who although often people go on about how much money he spent like he manged a PSG type buying of success - actually look at the figures of what they actually spent whilst he managed them and you will be surprised just how little it was - it made waves for two reasons only, ONE - Malaga are such a small team that when they spent money comparable to the mid tier spanish teams like valencia, sevilla etc then it was remarked on like some mega cash spend - which is honestly wasn't, and TWO - it made headlines due to Malaga being banned for FPP breahces - which everyone without bothering to find out assumed it was because they had spent a gazzilion pounds on players - in actuality they breached FPP not on transfre spending or for the wages being in breach of what was allowed, but for not being able to pay the clubs outstanding debts and the players wages.
Managed man city to a semi final and one they have a great chance in, won a league and two cups in 3 seasons, and had this season in the league pulled from under him by the appointing of Pep when they where sat 3 points behind leicester - the announcement completely derailed their season
Pelligrini a man who ahs reahced 1 SF, 1 QF and another SF - possibly final as they are still in it, with 3 completely different teams in his career, and your not keen on him because he hasn't won every signle thing with man city...
I prefer Mourinho as i have stated , but Pelligrini would be a massive statement to appoint him as manager and would be so far above the level of De Boer, Cocu etc
