No sooner had defensive midfielder Krystian Bielik arrived than he was thrust in front of a camera with not one, but two, Arsenal shirts. The way Mathieu Flamini has been playing of late, he'll be doing two jobs in that Arsenal central midfield as well.
The 17-year-old 'new Patrick Vieira' (no pressure!) becomes Wenger's first signing of the transfer window, and he is in contention for a first-team spot, according to the manager himself.
The fee is believed to be around £2.5m plus add-ons.
Elsewhere, Arsenal are reportedly closing in Villarreal defender Gabriel Paulista. Wenger confirmed earlier this month that a defender was a priority, and he looks good to his word.
Spanish newspaper AS is reporting that the player will put pen to paper on an Arsenal deal as the Premier League club has agreed a €20m fee for the 24-year-old centre-back.
Manchester United were also heavily linked with the Brazilian. Villarreal boss Marcelino seems resigned to losing his player.
"I have assumed the status of Gabriel; it's bad news from a sporting point of view," the manager said. "If both Gabriel and the club believe that a sale to Arsenal is what's best for everyone, we accept it."
More transfer news
The Telegraph reports on another transfer tug-of-war between Manchester United and Arsenal - this time over PSG striker Edinson Cavani.
French newspaper L'Equipe reports that United are exploring a possible swap deal involving Radamel Falcao and Cavani - although they'd have to make the Colombian's deal permanent this summer first.
Arsenal have long been quoted as Cavani's most likely Premier League suitors.
And finally, the Daily Star reports that Arsenal are planning an offer for Cheick Tiote, the Newcastle enforcer.
He's exactly the sort of player that Arsenal need, if a little crude in the challenge, but the report claims a £9m bid could be on the cards to test manager-less Newcastle's resolve.
