Seems to me they'd already decided bringing in a new manager in the off season (Mourinho house hunting anyone?) and that it'd be risky to let AVB get a last chance to turn it around, making it harsh to sack him at the end of the season.
What's this based on exactly?
Success as Man Utd reserve manager, coming in and winning the first league title in history for the club he went to after in his first season. Fergie saying he's the one to watch of his former students and so on. For starters.
What a "giggs" means ?
Basically that someone's saying something way after it's already been said. IIRC it originated when someone came on here ages after Giggs had done something to say he had done it.
Actually yeah, he wasn't that great during the World Cup. Guess that was a bad example then.
Diouf to Liverpool is a better example. (I think he signed after the WC, though I also think it might have been before. )
