I've been thinking about that myself. Schneiderlin may have been a little more ambitious at the time but I think he and Wanyama were both holding players first and foremost.
That Southampton team had a lot of player types we don't and there's a good chance that those other things are what made the two DM approach work, at least in terms of build-ups:
- two attacking fullbacks (Bertrand, Clyne)
- an effective box-to-box midfielder (Davis)
- a genuinely good creative passer (Tadic)
Maybe Tom Davies is a good box-to-box player (maybe) but we're currently hurting for fullbacks that contribute to build-ups and anyone who can pick a pass in the final third.
(Probably also helped their cause to have Pelle (target man) and Mane/Elia/Long (pace!!!) when they needed to play more directly.)
Plenty of players who could carry the ball up the field helps and a strong target man as well for when that isn't working.
Mane, Tadic, Clyne, Bertrand, Redmond, even Davis all get up and down the field well with good quick movement and most can carry the ball.
