Union Berlin are braced for summer offers for their star forward Sheraldo Becker amid mounting Premier League interest.
West Ham, Fulham and Burnley, who will be back in the top flight next season, are among the clubs who have been alerted by Becker's form for surprise Bundesliga package Union.
Union are on course to qualify for the Champions League for the first time and reached the Europa League last-16 this season, with Suriname international Becker their biggest source of both goals and assists.
Attacker Becker, who is valued at around £15m, has top scored for Union this campaign scoring 12 times and setting up 10 further goals in 46 appearances.
