Football Echo: On the Bounce: WHODUNNIT? W E now know it was that naughty Ashley Cole (or maybe Francesc Fabre- gas) who was the mystery pizza thrower of Old Trafford. But, undeterred by the fact my planned piece for today is now out the window, On the Bounce sets out to discover the answer to the really big question from Sunday's game: Who chucked the soup at Fergie?

JENS LEHMANN 

Occupation: Dodgy keeper for best team in land. Previous record: Well known to authorities as someone with a short fuse but, amazingly, no previous convictions of this nature.

Motive: Doesn't need one. Could start a fight in an empty tunnel. Fergie might have looked at him in a funny way or something.

On the Bounce verdict: Flammabletemperament makes him highly suspect, but experience suggests he'd probably drop the soup, then blame anyone with the cheek to stand within ten yards of him.

MIKE RILEY 

Occupation: Referee. Allegedly.

Previous record: As long as your arm when it comes to making bad decisions, but surely attacking Fergie would surely be too foolish even for him.

Motive: Hard to say. You'd think him and Fergie would get on quite well.

On the Bounce verdict: If it was the visiting manager, possibly, but as we all know, he's always very accommodating to Fergie at Old Trafford.

ARSENE WENGER

Occupation: Rival manager and Fergie's arch enemy.

Previous record: Completelyclean. Calm and unflappable under pressure.

Motive: Anything but calm and very flappable when it comes to his arch-enemy. There's something about Fergie that just causes him to lose it completely. Quite a few things, probably. On the Bounce verdict: Soup just seems too unsophisticated. A glass of Chardonnay might point to Wenger, but this seems unlikely. When Fergie's around, though, he's capable of anything.

WAYNE ROONEY

Occupation: United and England striker and part-time boy wonder.

Previous record: Involved in various scuffles over the years but, as a former boxer, probably more likely to have a proper fight than resort to food.

Motive: Boys will be boys, eh?

On the Bounce verdict: On paper an unlikely suspect, but the alleged presence of pizza amongst the items thrown does make you wonder.

A birthday prank which backfired, perhaps?
