Please tell us this perfect manager who always gets his tactics right all the time.
Is it Mr Ferguson, who failed to close out a 4-2 lead against Everton?
Is it Mr Mourinho, who sticks rigidly to his system of Alonso and Khedira, ignoring Modric?
Or is it Mr Klopp, whose team have been superb in the Champions League this season, but have a 1% chance of actually winning in the final, and only got there off the back of 2 late offside goals in the quarters. His team are 20 points behind in 2nd place.
Sometimes you have to just look at the players. If the players in one team is better than the other, they should beat them.
Only if you're inferior should you need a clever tactically trick to win.
