Pep was Barca's legend, a La Masia Youth product, team's captain in 00's and the Barca team he took over already had good core who'd worked in already perfect system (Xavi, Iniesta, Puyol, Messi, Eto'o, Valdes), all he needed to do was little bit tweaks here & there (mainly team spirits). Same can't be said about McKenna and our team.
I dont want to ruin the mood here & i know CAF have weird fetish with youngish players/managers (the younger the better is the mantra here) but can you logically explain, how an ex U-18 manager would suddenly be respected by season pro first teamers?
