'We've got fans on the pitch. The game's still going on'. That's not me making a mess of Kenneth Wolstenholme's infamous words from Wembley in 1966 when the boys in red won the World Cup. That was Jonathan Pearce's spontaneous reaction on commentary when some Villa fans piled onto the playing area towards the end of their team's semi-final at home to West Brom.
