The simple solution is to recruit players in the 24-28 bracket. But the ones worth recruiting are generally expensive. So I think we deliberately avoid this bracket and try to divide the legs & experience between the young players and the veterans, instead of recruiting the total package in one player i.e. Suarez/Sturridge.
PS
We have a number of players that are 24. These players are entering a phase in their career where they will be expected to contribute and lead the team. We have seen mixed results so far. Henderson/Allen have done well but the likes of Lovren/Sakho/Balotelli have not delivered.
Well, exactly: it's the simplest and most expensive solution. Not only do those players cost more, but they need replacing sooner.
Of course, there's a bit more risk signing younger unproven players, and a longer wait.for them to deliver. If Origi in a couple of years joins Borini in the failed/surplus to requirements category, and Sturridge's availability limits his contribution, that strategy won't have worked too well. But you really only need half of those younger players to work out, to make it a viable strategy.
In the longer term of course, we should reach a stage of regular CL participation, increased revenue and ground expansion to have the financial power to go out and recruit one or two peak-years players if necessary.
It's worth noting that this isn't really a new, FSG thing, too. Paisley bought almost exclusively players under the age of 24, too. Dalglish was 26 of course, and I think only Wardle or Ogrizovic was older than that.
