Anderson Luiz Schveitzer  Ânderson Luiz Schveitzer (sometimes spelled Schweitzer) (born 5 April 1974 in Florianópolis), simply known as Ânderson or Ânderson Luiz is a former Brazilian footballer who played as a defensive midfielder most notably for Internacional and Italian Serie B and Serie C1 clubs. In Brazil, he is sometimes referred as "Ânderson Papoula" (Portuguese for poppy) after he failed an anti-doping test, only to be later found out that the abnormal result had been caused by poppy seeds from a bread.  Ânderson started his professional career at Internacional in 1992, winning both the Campeonato Gaúcho and the Copa do Brasil, having played the first leg of the final against Fluminense as starter at the age of 18. He was remarked as having good marking and tackling skills, in contrast to poor passing. In 1997, under manager Celso Roth, Ânderson was having the best moment for his career at Internacional and attracting interest from other Série A clubs. On 29 November 1997, after a Campeonato Brasileiro match against Santos, he tested positive for morphine after an anti-doping test, being suggested that the player used heroin and fans stating such performances throughout the championship having being enhanced by the use of drugs since, at that time, Ânderson was the best defensive midfielder at Bola de Prata (championship best eleven). Ânderson also stated that he was innocent and had not even taken any medicine that could have caused abnormal results, even though the club board suggested that the pleaded guilty by the use of medicine so that he could face a shorter ban. Having known a story that soldiers at the Vietnam War were flagged in an anti-doping after eating poppy-made cakes, some journalists decided to take a proof and underwent the test moments after eating breads with poppy seeds, having high morphine level at the exams. The result was revealed to the club and the player, who later contacted the hotel in where they stayed for the match and found out that they had breads with poppy seeds in their menu, which had been eaten by Ânderson. The appeal from the ban was successful, but damage was already done: his performances have dropped after the scandal, leaving him out of the Bola de Prata and being surpassed by teammate Fernando; interest from Palmeiras (which would later win the 1999 Copa Libertadores) cooled down, as well as interest from a Spanish club.
