The former Wigan and Chelsea man craves 'revenge' on the Premier League.
The Argentine has been linked with Sunderland recently. The Daily Mail reported at the end of last month that The Black Cats will make an £8 million move for the player in the summer, if they survive in the Premier League this season.
"Yes. Now I have more experience. I found a new place where I can play happily and it gives me confidence.
"If I come back to England, it'd be a great revenge."
Despite being dubbed the ‘next Hernan Crespo’ it never happened at Chelsea and he moved on to Wigan.
In the summer of 2012 Di Santo turned down the opportunity to remain a Wigan Athletic player. He left England with a reputation for not exactly being a lethal goal-scorer.
However his excellent attributes have seen him play for the Argentina national team and he is now in top form in Germany.
Di Santo has scored 13 goals in 24 appearances this season, a massive improvement from his time in England.
Still only 26-years-old, he would be an excellent buy if Sunderland do end up getting their man.
