Union Berlin are encouraging Premier League interest in Sebastian Andersson.
The Sweden international is up for sale at Union and a target for David Wagner's Schalke.
However, Kicker says Union would prefer to sell to an English club as Andersson's buyout clause jumps by 30 per cent for Premier League teams.
A price in the region of €5m has been mooted, with Union manager Oliver Ruhnert eager for a quick sale: "To have a certain team security and planning it needs to be done as early as possible. If such a player suddenly went out of the squad on October 1st, it would be difficult."
