Nice coach Claude Puel has announced goalkeeper David Ospina has completed his move to Arsenal.
Reports have linked the Gunners with a move for the 25-year-old since his impressive World Cup displays with Colombia.
And speaking to Sky Sports News after Nice's friendly defeat to Brentford, Puel claimed ignorance of the fee involved but said: "It's confirmed, yes.
"It's a good affair for Arsenal because he's a very good player. You will see next season the quality of this player."
Despite Joris Delle - Ospina's likely replacement after returning from a loan spell at Cercle Brugge - suffering a cruciate knee ligament injury in training this week, Ospina has been allowed to move to north London.
And Puel continued: "It's fantastic for him. It's important for him to try another league, another club and Arsenal is a fantastic club for him.
"David Ospina can take the goalkeeping position at Arsenal because his qualities are very strong and... magnifique. You saw in the World Cup how important a goalkeeper he is.
"For me, David can impose his quality, he's a goalkeeper who is very good with the feet, with his arms, he knows football and he's a very, very good player."
Another player expected to move to the Emirates Stadium is Southampton defender Calum Chambers, with a £16million deal understood to be under discussion.
Following hot on the heels of the signing of fellow right-back Mathieu Debuchy from Newcastle, the Chambers move would impact on the future of Carl Jenkinson - a situation which has not gone unnoticed by Hull boss Steve Bruce.
Bruce has enquired about a loan move for 22-year-old Jenkinson, who made his England debut against Sweden in November 2012 having represented both the Three Lions and Finland at youth level.
"I had a conversation with Arsenal four or five weeks ago to say 'would it be possible?', and apparently it might be," said Bruce. "We'll look at that situation.
"We haven't had confirmation from Arsenal and I would hate to upset them by speaking out of turn but we are led to believe the kid might be available for loan.
"If he is, then of course we would be interested."
Jenkinson is not the only full-back on the Tigers' radar, with Andrew Robertson close to completing a move from Dundee United.
"We've got an agreement in place, the boy's travelling down tomorrow with his representatives," Bruce said.
"We think he's an exciting player, he's had a meteoric rise and we think he's going to be a really, really good player, so let's hope we can get it over the line.
