Chelsea striker Romelu Lukaku could be on his way to Werder Bremen in the summer as part of the Marko Marin deal.

A fee has been agreed for Marin and the deal will be concluded when the transfer window re-opens in the summer. Sky Germany are reporting that Chelsea will pay in the region of €8m (£6.5m) for the 23-year-old.

Lukaku, signed for £17m from Anderlecht last summer, could go to Bremen next season on-loan as part of the deal.
