Yep must be, another reason we need a main striker as well.
Not sure about this knee business, didnt seem to affect him for WHU, just how bad could it be?
Like I've said, as long as it's a sensible contract arrangement, should be okay. I'd be confident in Ba coming in as our number two striker in the event of injury/ switch to a 4-4-2.
My reservations do come from his apparent knee problems. So, think I'll go with what you're saying.
