since when are deep midfielders needing to be quick and agile? matic, carrick, schneiderlin, j martinez, busquets, kroos, schweinsteiger, alonso, cesc arent the most rapid guys around but theyre pretty good midfielders. id say positioning, distribution, and size are what we need. pace and power are a bonus, but youre pretty much asking for patrick vieira if you want a player that ticks all the above
