While watching yesterday's game yesterday, my fellow Addict writer and I disagreed on the form and performance of Alex Song.
He considered the young Cameroon midfielder to have been largely anonymous, while I thought he had been impressive.
In much the same way as Gilberto in the past, his is not a position that requires fire and guts at all times. Gilberto's nickname for the Brazil national team was, after all, the ‘Invisible Wall' and I thought Song did a very tidy job of winning the ball and letting the flair players do their thing.
Against Bolton a few weeks ago, Denilson looked pretty impressive, and he also had a part in the goal that beat West Brom. But I am still struggling to see how he is going to fit in.
Let's be honest, Cesc Fabregas is a shoe-in, assuming he is fit.
So that leaves one or maybe two other places in central midfield.
I'd like to think Song has what it takes to fill the Mat Flamini mantle this year - he needs to learn that following his man rather than crude shoulder charges which bring bookings is the best way to go (he committed this foul against West Ham and Fenerbahce and the best ball-winners are cuter than that).
So if Arsène Wenger wishes to play one more midfilder with Manu Adebayor or whoever up front on his own, who would fill the other midfield role?
In terms of impact and creativity, surely it has to be Abou Diaby, whose roving runs and assists in the two games previous to Sunday's Hammers win show what a talent he can be, if only he remains fit.
And if Diaby isn't fit, hasn't Aaron Ramsey already shown us glimpses of the exciting future he has ahead of him?
For me, Denilson does not do enough creatively to warrant a place. The fact that I'd prefer to see Ramsey in there underlines a lack of confidence I have in our young Brazilian.
My fellow Addict contributor is confident that Denilson will come good and prove me wrong - and I hope so too, but currently I don't feel he doesn't offer enough impact to really justify a starting place.
Interestingly, he wasn't even in the squad for the West Ham match, which suggests he's injured despite nothing having been made of it.
