Denis Suarez will join Arsenal on loan from Barcelona.
Barcelona announced the news in a statement, but it was later removed on Wednesday evening by the La Liga club.
The statement revealed that Suarez, who has one cap for Spain, has also agreed a new contract with Barcelona to protect his market value should a permanent move to the Emirates not work out, with his new deal expiring in June 2021.
Suarez also posted a goodbye message to the Barcelona squad on social media on Thursday.
He will link up again with Arsenal boss Unai Emery, who he worked with during a loan spell at Sevilla during the 2014-15 season. Arsenal will be paying Suarez's wages during his loan spell.
Suarez played 71 games in three seasons with the first team at Barcelona, scoring eight goals and has won five trophies: La Liga, two Copas del Rey and two Spanish Super Cups.
