You can't judge players solely by a set of fucking statistics. Jonas is shit at crossing and can't shoot for sausage, but he beats players, takes the pressure off the defence and at least makes the defender have to bother running after him, and as mentioned he wins free-kicks.
Duff however, will probably score a goal or 2 more than zero but contributes asbolutely fuck all else. He completely ruins the momentum of any attack by turning back and passing all the way back to the goalkeeper from the oppositions 18 yard box, and most importantly he's a stupid irish cunt.
