Sporting Lisbon have reportedly made a move that could be seen as a preparation to sell Viktor Gyokeres.
Gyokeres has been linked with the likes of Manchester United, Newcastle United, Liverpool and Arsenal in recent months.
The 26-year-old managed to score an impressive 42 goals in 50 games last season for the Portuguese giants.
Coventry inserted a 15 per cent sell-on clause into the £20million deal that saw Viktor Gyokeres leave the club for Sporting Lisbon last summer.
Portuguese outlet Record reports that Sporting have now paid €2million to reduce that sell-on clause to 10 per cent, which can be seen as the club preparing to sell the Sweden international.
