Paul Merson has identified the fatal flaw in Mikel Arteta he feels cost Arsenal the north London Derby - and possibly a place in the Champions League.
Gunners great Merson, who won five major trophies with the club as a player, reckons Tottenham are now favourites for the top four. They crushed Arsenal 3-0 on Wednesday night for their biggest ever win against them in the Premier League.
Arteta accused referee Paul Tierney, who sent off Rob Holding and awarded Spurs a penalty, of destroying the game afterwards. But Merson insists it was not Holding's red card or Tierney's performance that was to blame for opening the door to Spurs in the race for a Champions League spot.
