Mario Balotelli joined the 11th club of his journeyman career this summer.

After a short, goal-filled stint in Turkey with Adana Demirspor, the controversial Italian striker opted to switch allegiances to Swiss side FC Sion, signing a two-year contract in the process.

Balotelli has so far made two substitute appearances for his new club against FC Basel and FC St. Gallen, failing to score in either of them.

And it seems the former Manchester City striker's career in Switzerland has already taken a turn for the worse.

As reported by Swiss news outlet Nau Sport, Balotelli has not turned up to training this week after being caught leaving a bar drunk last weekend.

The player was caught on video in Lausanne looking a little worse for wear, so much so that he had to be supported by people as he walked towards a car park.

So, Balotelli has since not turned up to any of FC Sion's training sessions and the fact there's been no communication from the club on the matter suggests it could be a bit of an issue behind-the-scenes.

However, as Nau Sport have also pointed out, Balotelli has been active on Instagram since the footage of him leaving the bar drunk went viral.

He even uploaded a story to the social media platform from his official account on Thursday in which he appeared to be relaxing in a very luxurious location.

Maybe there's more to the story, although it would be rather strange if FC Sion had decided to give Balotelli time off from training, especially given the team are playing in the second round of the Swiss Cup against Rapperswil on Saturday.

Will Balotelli be in the squad for the match? It remains to be seen, but we'd be very surprised if he was named by manager Paolo Tramezzani given the circumstances.

Sion fans will be hoping the Italian striker's latest snippet of controversy doesn't have a huge bearing on his career in Switzerland, because there's potential for him to be a hit at the Stade Tourbillon.

As we previously mentioned, Balotelli rediscovered his scoring touch at Adana Demirspor after struggling to a degree at Brescia and Monza in his homeland.

'Super Mario' scored 19 goals and assisted seven more in 35 games with the Turkish outfit, which is a mighty fine return.
