Liverpool's Ivorian defender Kolo Toure said on Wednesday he is ready to prove that Arsenal made a mistake by selling him when his side face the Gunners on Saturday.
The Ivory Coast centre back joined Arsenal in 2002 and was a regular member of the famous "Invincibles" side that won the Premier League in 2004.
However, Toure was off-loaded to Manchester City in 2009 before joining Liverpool this summer on a free transfer.
"I'm going there to fight," Toure was quoted as saying by Sky Sports on Wednesday.
"I want to show them what I can do and help my team - Liverpool - to win. Right now I don't want to think about any of the good things that Arsene did for me as I'm focused on getting those three points."
"It's always special to go back there but at the same time I want to show on Saturday that Arsenal made a mistake by letting me go. I think it's going to be a great game for me to play."
Toure has also paid tribute to former boss Arsene Wenger, who brought him to Arsenal when he was 21 years old.
"I had some some great times there and it was a big part of my life. Without Arsene (Wenger), I wouldn't be here. He was the one who saw me," Toure added.
"He's a fantastic manager and gave me my chance to play football in this country. But now is not the time to talk about him. He knows I've been talking about him all the time."
