I'll be interested to see how Mandi goes with Burgess in front of him for a whole game; Burgess can do more of the running to make up for Mandi's lack of mobility.
I think it's fine to have a bit of a plodder in midfield with good technique, as long as the guys next to him aren't also plodders. Rufer is not really quick enough to make up for it, and neither is Singh.
Obviously a different level, but you look at a guy like Xhaka at Arsenal who moves like a truck and he performs badly when next to someone similar, but much better when next to someone like Ramsey or Torreira who are both quick movers with big engines.
