I totally agree. All this CDM and CAM malarkey is just modern day over complication.
I’m going to show my age now but imo the best midfield combination is a Souness type - a bit of a nasty so and so who’ll put his foot in when necessary but can also pass the ball efficiently (CDM?) and a Wark type who has the ability to attack the box at the right time and score a few goals (CAM?) The two examples I’ve picked were obviously masters of their trade.
Under Dennis Smith we had Smith and Gray in midfield. Neither were spectacular but they worked hard and efficiently. We didn’t do too bad with them did we?
