Borussia Dortmund centre back Sokratis Papastathopoulos is holding off on negotiations over a new contract as the Greece international wants to be sure that the Black and Yellows will qualify for the Champions League, something which has attracted interest from across Europe.
But the Premier League duo could face competition from Juventus as the Old Lady look to freshen up their ageing back line.
German outlet RevierSport claim that Sokratis is delaying contract talks at the Westfalenstadion until Dortmund's place in next year's Champions League is decided.
The report suggests that an offer of €20m would be enough to secure Sokratis' signature this summer as Dortmund could risk losing their star defender on a free transfer in 2019.
Peter Stöger's side are currently four points inside the top four, but results this weekend could leave Dortmund dangerously close to dropping into the Europa League places - with RB Leipzig, TSG Hoffenheim and Eintracht Frankfurt all within touching distance of Champions League qualification.
Lot of talk about Sokratis over a few Instagram posts. A new contract would be weird. 30-year-old 3rd-choice (should be) CB that could get you some nice money for the squad overhaul. Seems like an easy decision.— Lars Pollmann (@LarsPollmann) April 20, 2018
And it is this uncertainty which has alerted potential suitors to Sokratis' future in Germany.
Arsenal are in major need of defensive reinforcements this summer. Sokratis would not only add some much-needed quality to their side, but the 29-year-old would act as the perfect mentor for Konstantinos Mavropanos - a Greece U21 international who joined the Gunners in January.
Both Manchester United and Juventus have two of the best defensive records across Europe's top five leagues, but both sides will want to bolster their options even further if they are to push on next season.
