Sunderland striker Ignacio Scocco has completed his move back to former club Newell's Old Boys.
The 29-year-old, known as "Nacho", has returned to Argentina following a short, but disappointing spell on Wearside.
Scocco joined the club from Brazilian outfit Internacional for £3.2million in January, and is understood to have left for slightly less after failing to score in his eight appearances for the Black Cats.
Newell's Old Boys have confirmed the signing of Sunderland striker Ignacio Scocco.
The 29-year-old, known as ''Nacho'', arrived on Wearside in January as Poyet invested £3.2million in his services in the search for goals to keep the Black Cats in the Barclays Premier League.
Ultimately, it was a gamble which did not pay off as Scocco made only eight appearances and failed to find the back of the net.
Liverpool have agreed sell striker Fabio Borini to Sunderland in a deal reported to be worth £14m.
Borini, 23, spent last season on loan at the Stadium of Light and his crucial goals helped them avoid the drop.
Former Everton midfielder Tim Cahill is in line for a surprise move back to the Barclays Premier League.
Reports suggest significant interest from both QPR and Sunderland, as well as number of other top-flight clubs in the Premier League and also across Europe.
Sunderland new boy Costel Pantilimon is gearing up for a month-long battle with Vito Mannone for a place in Gus Poyet's Barclays Premier League team.
– Costel Pantilimon speaking to the Sunderland Echo
At this moment, I think everyone is fighting for their position. There's a long period until we start the Premier League.
It's normal for everyone to work hard, train hard and after that, we'll see what happens. I think everyone wants to be in the first XI. We'll see.
Vito is a good guy and a good keeper. I know that. But whatever happens, it's important that it helps the team.
It's not just competition for us, it's everyone in the team. At this moment, no-one is in the starting XI.
Sunderland head coach Gus Poyet is confident striker Jozy Altidore will be fit for pre-season despite having his World Cup ruined by injury.

From the beginning, the doctor has been in touch with the US medical staff.
In the beginning it looked bad but it got much better during the weeks and Jozy was nearly available for the [last 16].
If, say, the US had got through to the next stage, Jozy would have played a part.
We know hamstring injuries are tricky and that you have to be careful not to come back too quickly.
I am sure, if nothing goes wrong, that when Jozy is back with us for pre-season, he is going to be fit to start training without any problems.
