Arsenal already have one of the Premier League’s best duos in central defence, but are aiming for the next big one. We remember how Saliba established himself during his first season after his loan spell at Marseille, now a 21-year-old is being brought in with what is described as a similar potential.

At the beginning of the month, Caughtoffside’s sources reported that Arsenal were close to signing a very promising centre-back who is already delivering.

The 21-year-old already has 90 first-team appearances for Valencia, sources “close by” reported Mosquera had rejected Valencia’s offer of a new contract, signalling his desire to take the next step in his career with a move to the Premier League and specifically Mikel Arteta’s project at Arsenal. On Monday, The Athletic reports that only details remain before the Spanish centre-back at 1.91 can call himself an Arsenal player.

It is expected that the transfer fee will end up at up to 20-25 million euros. Personal terms between Mosquera and Arsenal are in place.
