#2 Pep Guardiola's philosophy is not without its release valves

Clue 1:Team A is leading Team B 2-1 with half an hour left to play. Manager of Team A takes of his sole striker and puts on a 6 ft + centre-back in his stead, pushing his central midfielder to play up top. Sort of.
With ten minutes to go, Team A are still holding onto the 1 goal lead... so they decide that everytime they win a corner, they'll send the no-one up, and everytime they get into the final third, they'll keep it by the corner flag. And they do it - unashamedly, brilliantly, effectively -keeping it in the corner for as much as 90 seconds at a stretch as they killin the game dead.
Clue 2: One of those teams were managed by Pep Guardiola and the other by Jose Mourinho.
Question: Who was the manager of Team A in this scenario above?
Two scrappy goals scored from set-plays, expert gamesmanship on and off the ball, killing the game dead when the game needed some hard killing dead... Pep Guardiola's men did all this and more as they proved their manager right - he and Mourinho are both twins when it comes to the matter of winning trophies... and both will do anything necessary to achieve it, even if it means a bit of philosophy has to be tossed to the wolves.
