Pablo Daniel Osvaldo joins the Premier League with something of a reputation.
The controversial striker shunned interest from the likes of Tottenham, Inter Milan and Atletico Madrid to complete a switch to ambitious Southampton, after the south coast club paid over £12 million to secure his services.
Whilst this signing is clearly a signal of intent from Mauricio Pochettino's side, Osvaldo comes with a warning.
Known for his unpredictability and volatile character, Osvaldo struck a calm and composed figure during his presentation to the media earlier today.
"I consider myself a very calm person and am very relaxed," he said. "There have been a lot of untrue stories in the media, some were true but they were exaggerated."
One of those stories centres around a bust-up between Osvaldo and AS Roma teammate, Erik Lamela.
After losing 2-0 against Udinese, the 27-year-old striker allegedly punched Lamela in the team dressing room for failing to pass him the ball. A €50,000 fine soon followed, and Osvaldo was subsequently suspended.
One thing is for sure, Osvaldo adds some much-needed charisma to the Premier League, which got us thinking of some of the other 'bad boys' who have featured in England's top tier.
