Arsenal have signed Deportivo La Coruna forward Lucas Perez for £17.1m.
The 27-year-old was close to joining Everton before the Gunners met the 20m euro release clause in his contract.
"He's not only a goalscorer, he's a guy who combines well with partners, who can give a final ball and makes good runs," said Wenger of Perez.
"He's got a good eye for goal and had an outstanding season last year."
