Lot of talk about where Erikson will play but I'd say at 10.
Going old school here - de Jong is a 6, Bruno a 7 and Fred an 8.
I happen to think Ronny will stay and be happy, but Bruno is a feasible alternative at centre forward, or off the centre forward, when he doesn't play or if he leaves.
Loads of options.
Martinez seems a genuine one at DCM, although with him at the centre of a back three could be an equally flexible position.
Irrespective of whether Ronny stays, I'd say forget going for a forward and get the de Jong deal sorted.
Then we're more than good to go.
