Manchester City face a potential financial crisis with midfielder Samir Nasri, after it was revealed that he could be banned for up to two years for drug violations.

The £120,000-a-week midfielder, 30, who is currently on loan at Sevilla, is surplus to requirements at City and the subject of a UEFA probe into an alleged breach of doping rules.

According to Daily Mail, investigation was launched after a bizarre incident last December in which Nasri is said to have used the IV drip to maintain his hydration and health for the season.

Nasri made a visit to an LA intravenous therapy clinic, who provided him with an IV drip.

However, the practice is banned by the World Doping Agency unless administered in quantities of no more than 50 milliliters per six-hour period, or when a certificate of special dispensation on medical grounds has been obtained.

If found guilty, the Frenchman could face a two-year ban, meaning Pep Guardiola’s side are stuck with a player they have already deemed surplus to requirements.

According reports, Nasri have been linked with a lucrative move to China, while Turkish giants Besiktas and Galatasaray have also been named as potential bidders, along with AC Milan.
