Yes Mossto is a "fox in the box" but has been played with guys with lesser ability like Ode and has had to come out of the box to support him. Play him with Macken and he can stay in poacher position and wait for the ball in the fox in a box positions.
Except I wouldn't drop Ferenczi from the team W've missed his work rate and closing down of the ball.
No, I'd stick with 2 I was meaning that maybe Macken and Mostto may be a good pairing but I don't see how Ferenczi could be left out just to try something.
