London, April 4 : Viagra seems to be gaining popularity among footballers, with a club deciding to give its players the impotence pill to help them play better in high-altitude cup matches.

Brazilian side Gremio has plans to use Viagra when they take on Bolivian teams, who have grounds up to 2,500 metres above sea level, in the Copa Libertadores.

Given that Viagra improves blood circulation, the club believes that it may boost the players' performance.

"I had this illumination reading a magazine. We did a scientific test," the Sun quoted club doc Alarico Endres as saying. (ANI)
