Juve's Pereyra is said to be interesting four Premier League clubs
West Ham are said to be keen on Pereyra - a winger-cum-attacking-midfielder currently of Juventus - despite reportedly agreeing a £12 million deal for Besiktas wide man Gokhan Tore.

The report claims Pereyra is looking to quit Juve over a lack of opportunities - though the presence of Dimitri Payet, Michail Antonio and Manuel Lanzini at the Olympic Stadium suggests a move there would be a case of out of the pan and into the fire for the 25-year-old.
That would not be a problem with either Sunderland or Stoke, however, as doubts surround the futures of Mackems wingers Sebastian Larsson and Jeremain Lens, while Potters star Marko Arnautovic, who has a year left on his contract, is stalling on a new deal.
