From The Sun:
'The French star fell theatrically to the ground under a second-half challenge from Didier Hamann, despite the German’s foot being well away from him. But, having already been booked, Vieira quickly realised the error of his ways and waved a hand of apology to referee Alan Wiley. Wiley could have produced a second yellow card but let the incident go. Vieira’s booking for clattering Xabi Alonso, his fifth of the season, has put him out of the massive Highbury showdown with Chelsea on December 12.'
Did Wenger see it? Will the FA's new Chief Exec insist on action being taken against Arsenal? No chance, there won't even be a media investigation but if one United player puts in a strong tackle on Wednesday night all hell will break lose.
