I think it plays out as:
1. If he turns out to be the new Messi we will want to shoot ourselves.
2. If he turns out to be as good as an Aguero we can look at the amount we received (if he's as good as Augero we get the add ons) and consider how we re-invested the funds. Could be good / could be bad.
3. He turns out to be a decent ten goals, ten assists a season wing-forward. Surely we re-invested the £35m better.
4. He fails to handle the expectation combined with the ~£10m /year salary and under performs. Happy days.
No?
1. Sterling? New Messi? One of the best ever? LOL. Never.
2. I can't see him reaching Aguero's level, but it's possible. I think it's the highest possible ceiling of his talent. Right now, the boy can't strike a ball cleanly. Technically he's got a lot of room for improvement. If he does improve that aspect of his game, then he could become world class. Will he be afforded the game time and patience he got at Liverpool with such a huge price tag and a manager's job constantly under threat? I don't think so. People don't understand how much of a good thing they have going at Anfield. Liverpool is such a great platform for many a career. We are continually giving players a platform to shine. Coutinho is going to be the next one (and he will no doubt be sold for 40 odd million in a few years to Barca).
Whatever way we look at 49m for Sterling, I think it'll only be considered a good value if we use the money wisely. In the past, that sort of money could buy us a young Torres and a young Suarez. Or we could waste it on another young Carroll. I'm encouraged by the fact that we're receiving this money now, and not at the end of August. Hence, the chances of a Carroll-type-panic buy is greatly reduced.
