Borussia Dortmund have reopened talks with Chelsea target Roman Burki.

The Blues were linked with a surprise move for the 29-year-old last week.

But German publication Ruhr Nachrichten says Dortmund are moving fast to tie up the Swiss goalkeeper.

Frank Lampard is reportedly on the lookout for a replacement for Kepa Arrizabalaga.

But he might have to move onto other targets, with Burki happy to stay at Signal Iduna Park.
