Was Toure's intervention a telling sign for City?
Defending higher up the pitch is not a new concept by any means but it has become more notable recently because of the way Pep Guardiola's Barcelona side has employed the tactic so effectively.
England boss Fabio Capello adopted a similar ploy in the recent Euro 2012 qualifying victory over Wales after making his players watch videos of the La Liga champions.
And in a season where his team has been criticised for being too passive, Manchester City manager Roberto Mancini used the tactic to great effect as his side recorded a surprise FA Cup semi-final win over Manchester United on Saturday.
The winning goal, superbly taken by City's Yaya Toure, was a case in point. The Ivorian intercepted Michael Carrick's pass outside the box before rounding Nemanja Vidic and slotting the ball past Edwin van der Sar on 52 minutes.
Carrick has been roundly condemned for his ill-judged pass in the build-up to the goal but credit should also go to man-of-the-match Toure, who nipped in to pinch the ball before it reached Paul Scholes.
Former Barcelona midfielder Toure had grown frustrated with a lack of appearances under Guardiola but he spearheaded City's five-man midfield at Wembley, proving he is much more than a defensive midfielder.
United manager Sir Alex Ferguson was aware of Toure's threat before the game as he employed a 4-5-1 formation against City, with Park Ji-Sung operating ahead of Carrick and Scholes in the midfield.
And it appeared to be the right move as United dominated the early exchanges and created two clear goalscoring opportunities, both spurned by Dimitar Berbatov.
But then City started to press their opponents higher up the pitch and, similar to the Liverpool side which beat United at Anfield recently, the Eastlands outfit began finding gaps between their opponent's deeper central midfield pairing.
"Maybe we had some fear in the first 20-25 minutes," said Mancini after the 1-0 success. "In the last 10-15 minutes of the first half, we started to play high, we started to press. In the second half, we dominated the game."
The resurgence was epitomised by Gareth Barry, who, along with Nigel de Jong, was the most successful tackler in the City midfield.
As for Toure, his involvement increased dramatically after the half-time interval. The number of times he touched the ball went up markedly, backing up City keeper Joe Hart's claim that the Ivorian was "fired up" and desperate to get a grip on the game.
Perhaps more telling was the number of interceptions made by City. In the first half, they managed eight compared to United's two. In the second, they made 16 to United's 10.
Then there was Carrick's passing accuracy. That fell from 92% in the first half to 74% in the second. Was that down to bad decision-making or because City's players were better positioned to pressurise and take advantage?
"Pressing high up the pitch is a risk and reward strategy," says former Arsenal full-back and Match of the Day pundit Lee Dixon.
"If it works - and it is hard work both physically and mentally - then the rewards are big. You obviously win the ball back closer to the opposition's goal and by the fact you press in numbers you normally have more people around the ball, hence more options to attack.
"The down side is that it only needs one person not to be working for it to break down. If this happens then you are very susceptible to a counter attack having gambled with players high up the pitch.
"Barcelona are a good exponent of this method. They press immediately after losing the ball anywhere on the pitch for a few seconds. If they don't win it back then they regroup.
"That said, if you can get through their first wave of pressing then they are, in my opinion, open and vulnerable."
United's cause certainly was not helped by the 73rd-minute dismissal of Scholes for a reckless challenge on Pablo Zabaleta. Ferguson was also without the services of Wayne Rooney, who missed the game because of suspension, although City had to make do without their own talisman, Carlos Tevez.
But are we seeing a subtle change of focus in the evolution of Mancini's team?
City continue to delight and frustrate in equal measure. Sandwiched between the semi-final over United and a 5-0 defeat of Sunderland was an abject loss at Liverpool.
But what do you think? Are City starting to flourish under Mancini? And will the Italian's tactics ensure victory over Stoke City in the FA Cup final?
