Don't particularly rate Mutu (especially at your level) and Owen isn't all that great either.
I'd start with van Persie and Huntelaar and if things go wrong have Owen on the bench for something different.
With Dagoberto he's always been so inconsistent for me. Play him in a few games (maybe the cup but at least 3
Prem games.)
I'd sell Mutu and/or Dudin if he's not for you but keep Saivet: he's amazing!
Form is also a big factor, if your strikers in good form then play him.
I've confused myself now, I don't know about you!!!
