Arsenal and Manchester United could reportedly find themselves in trouble after Alexis Sanchez allegedly missed a recent drug test.
According to the Daily Star, anti-doping officers arrived at Arsenal's training ground before the attacker had completed his transfer to the Red Devils.
Sanchez was reportedly one of the players set to tested, but because he was in Liverpool sorting out his work permit, he was not present for the process.
It has been claimed that representatives from both United and the Gunners will need to explain to the FA why the Chilean was not available for the drug test.
FA rules state that detailed training plans need to be provided for players at the beginning of each week in order to ensure they are available for tests at all times.
As Sanchez was technically still an Arsenal player at the time, the North London club could be fined as a result.
On the football front, the Chilean is set to make his United debut in the FA Cup against Yeovil Town on Friday night.
Do you think Sanchez will be a success at the Red Devils? Let us know in the comments section below.
