Regardless of whether he's over his injury or not in terms of form, Owen is always one sprint away from a hamstring injury, and that's about the best you can hope for with him. No chance he'll stay fit for 30+ games imo and behind him, you need a capable striker in case he doesn't even manage 20. We sell Martins and we'll have to buy one, with the way prices are we're either going to have to buy another unproven foreigner who'll need a year to settle and will therefore get the 'Martins treatment' next summer, if he's lucky, or spend ridiculous money on some overrated English no-mark. £8m for Nugent ffs and don't get me started on Alan Smith.
Obviously, thanks to Shepherd's negotiating genius, we might not have much say in the matter.
