Arsenal have completed the signing of Cristhian Mosquera from Valencia in a deal worth at least £13m.
Mosquera has joined up with his new team-mates in Singapore after agreeing a five-year contract.
The deal for the 21-year-old, who underwent a medical in London, could rise with performance-related add-ons.
Mosquera had entered the final year of his contract at Valencia and turned down offers of a new deal because he wanted to join Arsenal.
Arsenal boss Mikel Arteta said: “As a 21-year-old defender, Cristhian has already performed consistently well with significant experience in La Liga. He is an intelligent player with good pace, who can play centrally and on both sides.
“He is a young player with exciting talent and enormous potential, who will fit well into our squad as we continue to prepare for next season.”
Gunners sporting director Andrea Berta added: “We’re very happy and excited to have signed a hugely talented young player in Cristhian Mosquera. We identified Cristhian as one of the strongest young defenders in European football, and he is an important signing for our future.”
Mosquera was born to Colombian parents in Spain and joined Valencia at the age of 12, going on to make 90 senior appearances and scoring one goal.
He has also made 11 appearances for Spain U21s, starting all of their games at this summer’s U21 European Championship before they were knocked out by England in the quarter-finals.
Mosquera is a naturally right-sided centre-back but has also played on the left and is expected to provide competition for both William Saliba and Gabriel Magalhaes.
Young, physical, composed – Mosquera has talent to be honed
Sky Sports’ Nick Wright:
One of the best indicators of Cristhian Mosquera’s quality can be found in the sheer number of minutes he has played. Since being drafted into the Valencia team at the age of 19 in August 2023, he has started 70 league games out of a possible 72.

Sky Sports News’ James Savundra takes a look at Cristhian Mosquera and breaks down how the Spanish centre-half compares to Arsenal’s other options
In probably the most challenging position on the pitch tactically, and with all the pressure of playing for one of the biggest clubs in Spain as they navigated a turbulent period, the young centre-back came to be seen as undroppable by two different managers.
His total of 6,394 minutes played across the last two seasons is the highest by anyone aged 21 or under in Europe’s top-five leagues. The volume of playing time highlights reliability and robustness. It also gave suitors such as Arsenal plenty to go on.
Clearly they liked what they saw, and they were not the only ones, with Bayern Munich and RB Leipzig also said to have tracked him. He heads to Arsenal with a reputation as one of the the most promising young centre-backs in Europe…
