Wenger has always been something of an expert at the surprise signing. You could never bet against him pulling a Frenchman with something to prove out of a hat. The ultimate ‘Abracadabra’ was Sol Campbell, who emerged like a mirage, grinning into the Colney sunshine. On that occasion Wenger allowed himself a wry smile in public, while behind the safety of his office door he was far more effusive, flicking his fingers and saying the word ‘sick’. Sol Campbell was the surprise signing benchmark.

So yes, Wenger likes a surprise signing. He really likes one.

But they’re becoming harder to do. The rapacious internet leaves no stone unturned. The web is a foreign language too far for Wenger. Imagine the chit-chat with Podolski. Wenger thinks #aha went downhill after Living a Boy’s Adventure Tale. It’s Oldie v Poldi.

But Wenger likes a challenge, and if he can defeat the internet and its binary inquisitiveness, then quite frankly it’s like a trophy to him. There’s a small glass of Dubonnet with his name on if he can sign a player for Arsenal from right under the nose of the internet.

That’s why I gave myself a small fist-bump when I switched Twitter on last night to read that we’re close to signing Calum Chambers from Southampton. “If this one comes good”, I said to myself while whistling suggestively, “Wenger’s defeated the internet again”.

Even if it doesn’t happen, Wenger’s back on form. Everyone knew (and hoped) about Sanchez before he came. Debuchy was common knowledge. The name of Ospina was a bit more Wenger, but Chambers has come from nowhere. It’s hallmark stuff from Le Boss.

People are taking it seriously because it comes from the BBC’s David Ornstein, who is pretty adept at separating wheat from chaff. If you don’t follow him already, you really should.

At 19, Chambers is very young. With only 25 appearances at the top level, he’s also very inexperienced. Being English, he’s expensive – I’ve read £7m and I’ve also seen £16m. But he’s versatile, being a right-back also able to play centre-half, much like Sagna. It makes sense in many ways. Debuchy number one, with a more inexperienced number two who can also fit in elsewhere.

That would leave Jenkinson with the fight of his life. Should this deal go through he’ll almost certainly go on loan, which is what he needs to kick on. Coming back to Arsenal would be tough, you’d think, a huge challenge. Ashley Cole was one of the few players to come back from loan a better player, but he was far younger than Jenkinson.

Anyway, we shall see. I’ve enjoyed this summer so far, what with the World Cup and some Arsenal business cooking nicely. There’s a sense of urgency and a dynamism this year that felt absent for most of the summer of 2013.

Long may it last.
