I can almost imagine Arsene being asked out by his wife for dinner:
Arsene's wife: Arsene, do you want to go for dinner tonight?
Arsene: There is interest, always, in dinner.
Wife: So where do you want to go?
Arsene: You know the place I want to go, but I cannot tell you much more than that.
Arsene's wife: So we're going to the Savoy?
Half an hour later Arsene returns with two big mac meals.
Wife: what's this!
Arsene: sometimes I surprise you.
The point of this attempt at comedy, is that whilst I think we will be getting a player in, it won't necessarily be one we've heard of before, or one we're expecting.
But the fact Arsene seems to realise we still need another body is promising in itself. The talk of Gareth Barry coming in seems too obvious to me, although given his appearance in the Uefa cup, his price will have come down, making a deal possible. He would also be available in the second half of the Champions League, and the squad should be strong enough to get through the group stages without him.
On the other hand, this talk of snapping up Barry could be an attempt to force Liverpool into action, allowing us to make a bid for Alonso. Personally, I think Alonso is too similar to Cesc for that partnership to work. Barry, on the other hand, could prove a natural defensive foil to Cesc, if he continues his form of the last few seaons; and that's a big if.
Or, this could just be a case of Arsene toying with English journalists before he buys someone we've never heard of, or barely heard of, before. Gokhan Inler might be at the top of this list.
In any case, I don't think the cheque book is closed just yet. And the addition of a decent central midfielder to the squad could turn a rather average transfer window into a very successful one.
