Borussia Dortmund are maintaining interest in Manchester City striker Edin Dzeko as the German side look to strengthen ahead of the possibility of losing several players this summer, The Daily Mail reports.

The Bosnian is eager to secure regular first team football and is open to offers in January.

Dortmund are reluctant to spend over £15million which is below City's valuation but want a replacement for Robert Lewandowski who is destined for Bayern Munich.

They also expect a bid from Manchester United for midfielders Marco Reus and Ilkay Gundogan.

German international Reus enjoyed an outstanding season for his club last year, scoring 19 goals from midfield.

Then 24-year-old has a £29.4million release clause which Moyes hopes to offset with the inclusion of Kagawa who has struggled to make an impact at Old Trafford since his move from Dortmund 18 months ago.

Reus' Dortmund team-mate Gundogan could also be included in the deal. The playmaker joined the German giants two years ago but has made only three appearances this term.
