Chelsea have enquired about Inter Milan defender Martin Skriniar in a swap deal that could involve striker Romelu Lukaku returning to his former club in Italy.
Blues boss Thomas Tuchel is eager to bring a new central defender this summer following the departures of Antonio Rudiger and Andreas Christensen, with Skriniar now viewed as a potential option for the London club.
Inter Milan have already turned down Paris St Germain's £43million for the highly-rated Slovak but could be more open to doing a deal with Chelsea with the Italian club keen on Lukaku returning to the San Siro this summer.
