Chelsea's opening offer for Haaland turned down by Dortmund

Borussia Dortmund have turned down Chelsea's opening offer for striker Erling Haaland, according to Sky in Germany.

Chelsea offered Dortmund either Tammy Abraham or Callum Hudson-Odoi in part exchange for Haaland, but the Bundesliga side are determined to hold onto the 20-year-old.

The club are keen to sign a new striker this summer after struggling in front of goal at times last season.

Despite winning the Champions League, Thomas Tuchel's side lacked a reliable presence in the penalty area, with Timo Werner and Abraham's 12 goals each making them the club's joint top scorers.
