Chelsea are just one of the leading European clubs interested in Bayern Munich defender Niklas Sule, according to reports in Germany.
Blues boss Thomas Tuchel is keen to bring about a defensive overhaul in the summer transfer window after joining the club last month following the sacking of Frank Lampard.
Germany international Sule has been one of the names linked with a move to Stamford Bridge in the club's search for a commanding centre-back.
And according to German outlet Abendzeitung Munchen, Tuchel's side are just one of several top clubs monitoring Sule's situation at the Bundesliga champions.
