Chelsea are reportedly prepared to make bids for Ajax pair Andre Onana and Nicolas Tagliafico.
After regular poor performances in defence throughout the most recent campaign, Frank Lampard is eager to make significant changes during the summer transfer window.
While Atletico Madrid goalkeeper Jan Oblak and Leicester City left-back Ben Chilwell have both been linked with a switch to Stamford Bridge, their respective valuations are said to be out of Chelsea's price range.
According to The Mirror, that has increased the chances of the Blues moving for Onana and Tagliafico before the beginning of the new season.
Should they be able to reach agreements for the duo, Chelsea would effectively be saving in excess of £100m when taking into consideration what they would need to pay for Oblak and Chilwell.
The Premier League outfit are no strangers to holding talks with their Ajax counterparts, having already signed Hakim Ziyech from them this year.
