Arsenal and Chelsea are reportedly preparing to go head to head for the signature of Barcelona centre-back Samuel Umtiti during this summer's transfer window.
Barca are allegedly open to selling the France international ahead of the 2020-21 campaign.
A recent report claimed that Umtiti's knee problem, which forces him to have synovial fluid drained from the area every month, was putting off potential buyers.
However, according to Mundo Deportivo, both Arsenal and Chelsea are weighing up summer moves for the 2018 World Cup winner.
The report claims that the centre-back has been a long-term target for the Gunners, while Frank Lampard's side would have allegedly attempted to sign him last summer had they not been under a transfer ban.
The Spanish champions allegedly value Umtiti in the region of £46m.
