No ge~, to me Owen is must sell. No matter how good he is, it's impossible to have a striker that can only feature for at most half a season. Way too injury prone.
Cisse's case could be difficult to decide. But the first striker that should be sold is Morientes in my opinion. Very disappointing in these 2 seasons. He never really recovered the form Monaco. Always so slow and so tired to run on the field, and his moment of intellegence comes too rare to justify a spot in the starting lineup.
