Egypt's former Brazilian physiologist Ricardo Guererra is embroiled in a controversy over the medication he administered to national team members.

"It is not magic," he said. "All I gave the players were some vitamins, food supplements and Creatine."

"These are all completely legal substances under the guidelines of Fifa," Guererra told BBC Sport Online.

However, the EFA has terminated his links with the national team.

"The problem is that they are not used to having a physiologist in the Egyptian technical group, "said Guererra.

"Egyptian players are very talented and highly technical, but their physical conditioning and physiological capacity is poor," he added.

Guerrera vehemently denied giving the players any illegal substances.

"Before finger-pointing they should have tested the players and I dare them to find any player who is doped."

Rolling stone

The Brazilian arrived in Egypt last year and was initially hired by Goldi club, owned by business tycoon Ahmed Bahgat.

With Guererra's help, the team finished in sixth place, their best ever league position.

Mohsen Saleh, Egypt's national team coach, subsequently decided to include the Brazilian in his technical crew.

But the pill controversy appears to have forced Saleh to end Guererra's association with the team.

"I hired him just for our Nations Cup preparation period and do not need him any longer," the coach said.

However Guererra says officials are deliberately orchestrating a negative campaign against him in order not to pay him the two months salary he says he is owed.

Egyptian football has barely recovered from the Nations Cup drug scandal in Mali, when Hani Said tested positive for the prohibited substance Nandrolone.
