Liverpool striker Luis Suarez has extended his lead as the Barclays Premier League's top scorer after being awarded a second goal in last weekend's 4-1 win over West Ham.
The Uruguay international's strike from distance took a deflection off Joey O'Brien and went down as an own goal by the defender.
However, the Premier League's Dubious Goals Panel has now decided the goal should be credited to Suarez, who had already scored once in the game.
By contrast, Aguero's 12 have come in 14 league matches.
Suarez is set to face England at the 2014 World Cup and former Liverpool player and manager Kenny Dalglish, who signed the striker from Ajax in January 2011 for £22.85million in his second spell as Reds boss, believes he will terrorise England defenders at next summer's tournament.
"I would have thought that when the World Cup draw was made there were a few English defenders thinking 'Oh no, I've got to play him again - it's bad enough twice during the season'," he told liverpoolfc.com.
"You couldn't write the script. People glossed over the second goal he scored against Norwich because of the brilliance of the other three, but the technique for the second goal was fantastic as well.
"Luis has been fantastic. He's a great entertainer and he's a humble guy.
"He's somebody that really enjoys working in training, he is never a problem in training and he's fantastic on the pitch.
"It's a real joy to see him play sometimes. The goals he has scored have been hugely influential on the position that Liverpool are holding in the league at the moment."
