It's an interesting debate and I think some of it comes down to what you regard as the 'double pivot's' primary purpose or objective. If it is to detect, destroy and counter then a Maka-Toure partnership is preferable. If the prime emphasis is to hold and counter, then something like Ramsey and Wilshere may be preferable, although it hasn't escaped me that the former two have proved everything in the game and the latter nothing yet.
I do sense that our collective defensive strategy is based on strategically outnumbering opponents in midfield and pressing them at crucial times and in that sense a player in the Maka mould is less pertinent although obviously a valuable asset in any squad. So many of the goals we have conceded in the last two seasons have been down to individual errors, because what we do collectively works, when we are committed to it.
Wilshere can never be a Maka primarily because his skill set means no manager would ever use him in the exact same way. Ie, he has a lot more about him, but that is not to marginalise the positional understanding the little Frenchman had. It was quite profound and only second to his ability to thwart you. There can't be many players that it would prove more difficult to get past.
We need time to see how he develops but with Ramsey's numbers right now (as well as what we see with our own eyes) mean he can be played comfortably in any position. Anyone could slip into the double pivot with him and he can even be given the holding role on his own right now. He is covering that much ground, passing so well and winning that many tackles (95% so far this season) that it really opens the options up. He is basically coming away with the ball every time he pokes his toe out and that's without mentioning his goal tally. That's why you need to take a longer term view and keep an eye on how he does to determine where he might be in the long run. Encouragingly though, most these stats extend beyond the beginning of this season and into the back end of last. More evidence that it is genuine improvement as opposed to fleeting good form.
