Celtic and West Ham United are reportedly interested in signing Borussia Dortmund striker Julian Schieber.
The 25-year-old, who is out of contract in summer 2016, scored just one goal in 20 appearances for the Bundesliga club last season.
His future with Dortmund is now understood to be in the balance following the recent arrival of Ciro Immobile from Torino.
Celtic and West Ham could now battle it out to land the former Germany Under-21 international this summer, according to Goal.com.
Meanwhile, Wigan Athletic are also thought to be monitoring Schieber ahead of the new season.
