Hard to tell at this moment. Rasiak and John are both proven CCC and international players. If DM score more than 20 goals and get more than 5 assists this season, then he is better. The youngsters look like very good footballers but that doesn't mean Saganowski, Euell, etc are very poor. Saganowski scored 10 goals in half season for the play-off season, Euell is one of the good candidates since the arrival of NP.
I don't see Rasiak and John moving and passing a lot, but did you ever see Rasiak 's constant clinical finishing particularly the goal against Derby away? Did you see all the amazing goals that John scored especially the goal at home against Hull, Sheffield United, etc.
