Kolo Toure's positive drugs test is one of the "stupid things" in life that can trip up even the most conscientious of people, according to Arsène Wenger.

The former Gunner has been suspended after a "specified substance" was found in a routine sample he gave recently. Wenger has spoken to Toure since the news broke and gave the Ivorian a glowing character reference when the matter was raised at his pre-match press conference.

Wenger believes that Toure failed the test because he took one of his wife's diet pills to control his own weight and insists that there is nothing sinister about his old player's case. But the Arsenal manager admits that even the most ‘innocent' person can slip up unexpectedly.

"It was completely the kind of stupid thing that can happen to you, where you are punished in life," said Wenger.

"Cross the road, don't look right, left... boom. People don't ask if you deserve it or don't deserve it.

"I have spoken to Kolo and, of course, he is shocked by the situation because you know Kolo. He is a guy who never prepared himself to be in this kind of situation so it is a big shock for him.

"He wanted to lose weight a little bit and his wife was on a diet and that's where he took this product.

"He is devastated because you can be suspended once you are positive and people don't consider too much why you did it. They just punish you. It is a blow for Manchester City as well.

"It is [harsh if he gets banned] but legally, you know, what is forbidden is forbidden. The mistake he made is not to have asked the doctor of Man City, ‘can I take that or not?'

"You must say as well that he was unlucky because he was done in the doping control after Man United and he didn't play. That means he has one chance out of nine to be picked."
