The Court of Arbitration for Sport has rejected Samir Nasri’s appeal against a doping investigation, allowing UEFA to continue looking into the former Arsenal midfielder who faces a four-year ban.

I’m sure most football fans on Twitter remember Nasri’s visit to LA intravenous therapy clinic Drip Doctors.

If you don’t already know, the clinic posted a picture of the footballer with a caption claiming they’d given him an IV drip.

The World Anti-Doping Agency prohibit this treatment in quantities of more than 50 millilitres per six-hour period.

According to the Daily Mail, the Frenchman requested that UEFA grant him a backdated therapeutic use exemption.

The European footballing governing body rejected this request. Now the investigation can re-open, and Nasri faces a four-year ban if found guilty.

The Mail claim Manchester City let the 30-year-old move to Antalyaspor for free, because of the threat of a ban.

They only accepted add-ons and a sell-on clause in the sale.

As a result, Arsenal missed out on any money due from sell-on clauses of their own. Although Nasri spent some time on loan at Sevilla, this was his first permanent move since leaving the Gunners.

The midfielder signed a new five-year contract with City in 2014, so he still had enough time on his deal to command a decent fee and it’s likely that any Arsenal sell-on would have dropped with his new City deal (or possible been removed entirely).

Unfortunately the doping investigation clearly ended that possibility.

More than six years later, and Nasri’s decision-making could be still screwing Arsenal over.
