Real Sociedad's players were subjected to doping practices, according to the club's former president, a claim refuted by Westerveld.
Former president Inaki Badiola was around when the Liga club apparently struck off two doctors, Eduardo Escobar and Antxon Gorrotxategi, in 2008 because they discovered payments in the prior six years for products which were classified as banned substances.
Dutch goalkeeper Westerveld played at the Anoeta between 2001-2005, and he said: "Of course at Real Sociedad there were players who received intravenous injections before and after games,” explained the 38-year-old to Voetbal International.
“Considering all of the recent stories, I will not put my hand in the fire for anyone. But I never saw or noticed anything unusual that someone would have received.
“I never noticed anything that would improve my performance particularly.
“In 2002-03 [when La Real finished as League runners up], we did that with football of technical and tactical quality. Football is not about fighting at full throttle for 90 minutes.”
