Chelsea are understood to be interested in signing Borussia Dortmund defender Lukasz Piszczek.
The Blues are currently searching for a new right-back following the release of Jose Bosingwa.
Polish interational Piszczek, 27, could now be on his way to Stamford Bridge, according to The Sun.
The FA Cup and Champions League winners are also thought have Ajax's Gregory van der Wiel and Lille's Mathieu Debuchy on a shortlist of potential candidates.
