You'll be playing zonal marking then.

----------ST----------
------------------------
-----MC-------MC------
DML-DMC-----DMC-DMR
------DC--DC--DC------

I've been playing around with the formation and I've come up with this. It might totally suck in practice, though. You want to play more players in the centre, because that's where he's most concentrated, so I've only placed one player on each side. DL and DR don't cover much in zonal marking, so I've instead gone for DML and DMR, you're free to tinker around with the placement of players in the centre.
