Skysports.com understands several English clubs are targeting Bayer Leverkusen winger Tranquillo Barnetta this summer.
The Switzerland international, a regular in the Leverkusen side, is believed to have attracted interest from Wigan, Sunderland and Newcastle.
Tranquillo, primarily a winger who can also play as a defensive midfielder, arrived at the BayArena from native outfit St Gallen in 2004.
He spent a brief spell on loan at Bundesliga rivals Hannover before returning to establish himself in the German club's first-team.
The Leverkusen man scored both of Switzerland's goals in quick succession during their 2-2 Euro 2012 qualifying draw with England back in June.
