Arsenal have officially unveiled Fabio Vieira after announcing his £30million move from Porto.
The Portuguese midfielder is the Premier League club’s first major signing of the summer transfer window.
Vieira, 22, said he ‘couldn’t be prouder’ to join a ‘huge and historic’ club like the Gunners.
Manager Mikel Arteta said: “I am very excited that we have identified and signed such a special talent.
“Fabio is a very creative player that will bring high quality and versatility to our attacking play.
“We welcome Fabio and his family to our club and are looking forward to starting work with him ahead of the new season.”
Vieira, a namesake of legendary former Gunners midfielder Patrick Vieira – now manager at Crystal Palace – will wear the No 21 shirt.
He broke through at hometown club Porto and has made 75 appearances in all competitions across his three seasons with the Dragons, scoring 10 goals.
Technical director Edu continued: “We’re so pleased to have completed the signing of Fabio from FC Porto.
“Fabio is a player with special qualities who is comfortable with the ball in the final third of the pitch. We are all looking forward to working with him and enjoying his future contribution to Arsenal.
“We will now continue to work hard and are looking forward to finishing this transfer window as strongly possible.”
