SUNDERLAND have been linked with a summer move for ex-Chelsea and Wigan striker Franco Di Santo.
Reports in the German press today indicated that Sunderland are tracking the £8million-rated Di Santo, who is about to enter the final year of his contract at Bundesliga outfit Werder Bremen.
Di Santo, who made almost 100 Premier League appearances for Wigan, joined Bremen on a free transfer in the summer of 2013 - after there had been some speculation of interest from Sunderland - and has since netted 17 goals in 44 games in the German top flight.
Bayer Leverkusen, Borussia Munchengladbach and Wolfsburg are also mooted to be tracking the 26-year-old, with his contract situation potentially prompting a summer move.
Lee Congerton knows Di Santo after the Argentine came through the ranks at Chelsea, when the Sunderland sporting director was working with the academy set-up at Stamford Bridge - a route which saw left-back Patrick van Aanholt join Sunderland in the summer.
Sunderland will be in the market to boost their attacking options at the end of the season too if they avoid relegation, with only Aston Villa netting fewer Premier League goals than the Black Cats.
Meanwhile, Sunderland - along with Leicester, Swansea and Hull - have also been linked with Polish international winger Maciej Rybus.
The 25-year-old, who plays for Terek Grozny in the Russian top flight, is about to enter the final 12 months of his contract with the club and has a £2.4m buyout clause.
