Wigan Athletic boss Roberto Martinez masterminded a shock FA Cup final win over Manchester City, again proving he is a manager destined for greater things.

Martinez and his threadbare, relegation-threatened squad outplayed and out-thought the multi, multi-million pound City starting 11. Ben Watson headed in a corner in stoppage time to give The Latics the trophy.

Performing these kind of miracles with limited resources, has defined Martinez as a manager. He has not only proved that you can still play attacking, passing football and survive on a limited budget, but you can also win things doing it as well.

Wigan dominated possession against the English Premier League's second-placed team. Martinez's men usually do make the ball their own, by sticking to a patient, forward-thinking style of passing.

It's an attractive, thoughtful brand of football that other managers, despite having the luxury of more money, often shun. Martinez doesn't boast riches in the transfer market, but uses what he has to sign skilled, technical players who can execute his vision of attack.

Players like forward Shaun Maloney exemplify the way Martinez approaches the game. Maloney isn't a physically imposing player, but the pint-sized attacker is Wigan's chief creator.

It was his corner that produced Watson's decisive goal. Martinez has also mastered the art of tactical flexibility.

At times he has seamlessly morphed Wigan between 4-4-2, 4-3-3 and 3-4-3 formations, depending on the opposition. Yet while the structure sometimes changes the philosophy does not.

No matter how Martinez deploys his players, his fidelity to expansive, passing football does not waver. That adherence to his core beliefs is why Martinez will eventually succeed on a bigger stage.

Wigan likely face the drop this season unless Martinez can engineer another miracle. You'd be smart not to rule that out.

However, even if Wigan's FA Cup winners do suffer the relegation blow, Martinez has proved his readiness for greater triumphs in the future.
