Chelsea are reportedly ready to make a move for Manchester United goalkeeper Sergio Romero.
Frank Lampard is known to be in the market for a new shot-stopper amid question marks over current number one Kepa Arrizabalaga, who became the world's most expensive keeper when he joined but ended last season with the worst save percentage in the Premier League.
Chelsea are also understood to be interested in Rennes' Edouard Mendy, while they have previously been linked with Mike Maignan and Jan Oblak.
However, The Athletic reports that they have now added Romero to their list of potential targets, with Manchester United willing to consider offers for the Argentine.
Romero has spent his entire five-year United career as second fiddle to David de Gea so far, and first-team chances could become even rarer following the return of Dean Henderson from a loan spell with Sheffield United.
The 33-year-old would represent a cheaper option than the other goalkeepers Chelsea are looking at, with Mendy expected to cost at least £18m.
Chelsea are already the Premier League's biggest spenders this summer and are set to take their splurge to more than £200m with the imminent arrival of Kai Havertz in a club-record deal.
Leeds United, Everton and Aston Villa have also been credited with an interest in Romero.
