Reports are out claiming that Brazilian pair Taison and Wellington Nem have been put up for sale at Shakhtar Donetsk.
Calciomercato.com claims that Arsenal and Chelsea are both on red alert after the Ukrainian club made Brazilian pair Taison and Wellington Nem available for sale.
Shakhtar are keen to get rid with neither player figuring regularly this season.
Winger Taison, who joined from Metalist Kharkiv in 2013 for £12.4m, has made 36 appearances in all competitions but has been on the fringes in recent weeks.
While attacking midfielder Nem, a 2013 arrival from Fluminense, has featured just 13 times.
