Atletico Madrid have confirmed that Arsenal have paid Thomas Partey's £45million release clause, terminating the midfielder's contract with the Spanish club.
Atletico released a statement shortly before the 11pm BST transfer deadline on Monday confirming that Arsenal had activated Partey's release clause 32 minutes before the deadline.
With buyouy clauses in Spain paid directly to LaLiga and then forwarded on to the relevant players' club, there was no need for Arsenal to inform Atletico of their intent to activate Partey's clause.
A statement from Atleti read: "LaLiga informed Atlético de Madrid at 11.28pm on Monday that Arsenal representatives have paid Thomas Partey’s release clause at the sports association’s headquarters.
"The player has therefore unilaterally terminated his contract with our club, which ran until June 30, 2023."
In an unrelated deal, Atletico have also confirmed the signing of Arsenal midfielder Lucas Torreira on loan for the rest of the 2020/21 season.
