STOCKHOLM, May 17: Mats Wilander says he consumed cocaine unknowingly during the 1995 French Open. However, Omats Garle, head of Huddinge Hospital's IOC-approved doping lab, doesn't believe the former world No 1 player.

It sounds like a joke,'' Garle was quoted as saying yesterday in Aftonbladet, a Swedish tabloid.

Wilander, who captured seven Grand Slam singles title including three at the French Open in the 1980s, told a Swedish television channel on Thursday night that ``he didn't feel anything afterwards.

But he must have felt the effect of the drug,'' said Garle, who has reviewed the test results. Normally, you should be awake for most part of the night afterwards.

Wilander's three-month ban from the ATP Tour was front-page news in most Swedish newspapers on Thursday. Some papers criticised him for not admitting that he had used cocaine.

Bjorn Borg's former girlfriend Jannike Bjorling claimed the former five-time Wimbledon champion from Sweden tried cocaine once. Borg denied it.

Wilander and Karel Novacek, the Swede's Czech-born doubles partner in the 1995 French Open, were suspended three months after withdrawing appeals to the ban for failing drug tests.

The pair first denied allegations of drug use and said the ITF test procedures were flawed.

The players argued that their urine samples had been mishandled and alleged the ITF failed to provide evidence on which the charges were based.

But after reviewing the test results and related laboratory documentation, the pair acknowledged the positive results although they maintain they were unaware of the presence of cocaine in their bodies and said the drug was unknowingly consumed.
