It depends on whether we would forgo the Europa League by just sending reserves out. If we just focus on league like what we did last season we could and should be top4. However if we don't do so then I could see us finishing 6-8. Several positions are still lack of quality cover and say an injury to Cisse would bring us big trouble already.
In fact I strongly believe we should give up Europa League next season. We need CL to raise our status and wealth in order to attract more quality players, instead of dragging back by the Europa League.
