Arsenal manager Arsene Wenger has dismissed suggestions by former midfielder Paul Merson there was anything untoward in the club's medical treatment.
Merson, 43, claimed players were injected with a "yellowy product" and that Wenger himself had handed out "a dark tablet", which was super-strength caffeine.
Wenger said: "I cannot take that comment seriously."
He added: "I don't know how many players have played here over 15 years, 200 maybe; some of them stayed for 10 years. Paul Merson stayed with me for four months, so I think it is better you ask people who have played for five, six, seven, eight, nine years here how we behave medically."
Wenger added: "I personally give them nothing. If they don't want to take anything, they take nothing.
"If you find one player who I asked to take something, bring him here in front of me. If we give them something, it is multivitamins, magnesium, calcium or vitamin C like everybody else.
"Every year we have at least 20 doping controls. In 15 years we have not had one positive control. You think, really, I try to dope?
"If you find one player who I asked to take an injection to play one game, no matter how big the game was, I would resign on Saturday morning.
"It is absolutely ridiculous to put any suspicion on the way we treat the players and respect the players' health."
