Manchester City will reportedly have to pay out a record amount if they are to sign Ben Chilwell from Leicester City.
Guardiola is keen to bring in a new left-back ahead of next season due to concerns over Benjamin Mendy, who has endured another injury-hit campaign.
Leicester boss Brendan Rodgers rates Chilwell highly, however, and The Telegraph reports that, with the 22-year-old under contract until 2024, Man City face a serious fight to land their man.
A bid in excess of £75m will be required, it is claimed, which will surpass the amount Liverpool paid to make Virgil van Dijk the world's costliest defender last year.
Leicester have previously played hardball with the Citizens when locked in talks over Riyad Mahrez, who eventually cost Guardiola's side a club-record £60m.
