Of course there is a always a risk that a player will not work out - where they come from doesn't alter that fact.
The greatest managers with budgets in the hundreds of millions are deemed successful if 50% of their signings turn out well.
Similalrly, if an academy produces one first team quaility player in a season, that is a high success rate.
We measure up well on both those stats the past couple of seasons, but we can't depend on producing an entire first team squad from our U20s. Our model means we need to bring in older players that we can also develop and move on for a fee. The fact we need to sign free (or low fee) transfers means it will always be a risk. They need to have potential to develop while, at the same time, not featuring in the plans of their current employer. For every Kipré in that situation, there will be multiple Strakers. I think we've improved that ratio in the past couple of seasons.
