After working together with such great results at Espanyol, it was no surprise when Mauricio Pochettino tried to reunite with Dani Osvaldo at Southampton.
With 21 goals in 46 games under Pochettino at Espanyol, Osvaldo was hot property in the summer of 2011, and earned a big €15m move to Roma.
The Italian international may have scored 28 goals in 57 games for the Serie A giants, Osvaldo's record was fantastic - but his conduct wasn't.
A notorious loose cannon, Osvaldo reportedly punched Erik Lamela before having a huge bust-up with his manager Aurelio Andreazzoli, and Roma made the wise decision to flog him to Southampton, recouping the €15m they paid just two years earlier.
Under Pochettino, it was all supposed to change. He was back with a manager who had kept him on the straight and narrow and got him scoring goals.
Yet somehow, Osvaldo was even worse on the South Coast, and after a training ground fight with Jose Fonte, he was sent out on loan to Juventus after just six months, with the 28-year-old now playing with Inter Milan.
Again, Osvaldo is embroiled in a controversial situation having screamed at team mate Mauro Icardi for not passing to him against Juventus in midweek, and the Daily Mail suggest that new Inter manager Roberto Mancini has already had enough of the Argentine-born striker, and will send him back to Southampton this month.
Pochettino has since moved on to Tottenham, and new Saints boss Ronald Koeman is unlikely to want anything to do with Osvaldo despite his side needing a striker, and the Daily Mail also report that Sunderland will have an interest in Osvaldo if he does return to England.
The Black Cats could only muster one shot on target in Saturday's 1-0 defeat to Liverpool, and with Jozy Altidore set to head back America, a new striker is certainly needed.
Osvaldo could be that man, but he's such a divisive figure, that he could cause more harm than good as Sunderland bid for Premier League survival.
