Borussia Dortmund are expected to return with an improved offer as they continue their pursuit of England U21 midfielder Jobe Bellingham. According to Sky Germany, an initial bid of up to €25million (£21million) has been turned down by Sunderland following their promotion to the Premier League.

The Bundesliga side are reportedly working swiftly on a revised proposal, with a package worth €25million plus an additional €5million in performance-related bonuses believed to be enough to reach an agreement.a
