Toure returns to action tonight after a six-month drug ban.
He insisted: "I have gained a lot of strength from this hard time and I just need to focus on the future. It is really important to get back to what I love to do - which is football.
"People know I am not someone to try and cheat. I was really unlucky but all the people at the club and in Ivory Coast gave me a lot of support - and the most important thing is now I am back."
