While Wenger's impact on Ferguson has been largely entertaining, his impact on the English game has been enduring.

Look around the top clubs, United apart, and they have all gone down the foreign manager route, as did the FA with Sven-Goran Eriksson.

While England 'enjoyed' mixed results under the Swede, the disbanding of the Liverpool boot room and Chelsea's decision to plump for Portuguese after Dutch and Italian has reaped reward.

If imitation is the sincerest form of flattery, even Spurs have doffed their hat to Wenger having settled on Martin Jol after trying Christian Gross and Jacques Santini.
