I think you've misunderstood them tbh - he's not saying we use "anti-tactics" as that we defend and nullify the other team and grind a win, like Mourinho or even Benitez, as you've said yourself, but that he adapts his tactics and team selection to his opposition to play to their weaknesses and nullify their strengths while playing to our strengths.
Nullifying the oppositions strengths is usually detrimental to playing to our strengths .
Juande did a perfect job of balancing these competing requirements on Sunday .
The balance is going to be different for a weaker side like Birmingham but we should never underestimate the opposition like Grant and Terry underestimated Tottenham Hotspur .
