If was fit, could Timber play DM, with Cala inverting to make a double pivot?
You'd not only have 2 pwoppa CHs covering the back-line, but either could drop back into a conventional LB spot when required.
And given BW was originally an Eng intl CH, we'd be starting with 5 CHs which GG would have loved.
It's a bit like the idea that Tent Alexander Arnold can play centre mid...
The reason these players work are because they are NOT playing in centre mid but they invert and overload it at the right times from their main position. If Trent could play centre mid, he would be a centre mid. If Timer could play centre mid, he would play centre mid...
