If our initial aim is to secure another season (or two) in the Prem, (and then take stock) then we won't do that by thinking long term - we'll do it by adding high calibre 30 year olds (ish) who can deliver immediately. And the key positions will be a CB to partner Olsson, another striker to reduce our dependence on Odemwingie, a better GK and a RB.
Friedel could be one of the answers, so could AJ.
Thinking long term is what we did when we added Brunt, Mulumbu and Dorrans. All three showed promise early on but each of them had at least a season (or more) - usually in the Championship, before they became consistent, top notch Premiership performers (and in the case of Dozza we're still waiting, albeit confidently.)
In my view we need a mix of long and short term thinking
