PPL Oshea is what W Brown was a couple of years ago. He was Manutd's golden boy, an able defender who would have delivered on the long run but was crushed by two main reasons
1. Manutd pretended too much from him. Leading Manutd's backline at his early 20s was a mistake and fergie's claim of wes being 2 times better than Rio shows how (too) highly we expected from the lad
2 Injuries.
I believe in O Shea incredible capabilities, but throwing him in the lions arena at such a tender age will only dimoralise him. Remember than playing in the red devils's backline is a huge responsability. It will mean facing the best strikers in the world week in week out, and pretending the best out of him.
Wes had tasted it and I wont be surprized if Oshea would pass from a similar experience.
My opinion is to bring in a confirmed defender and introduce OSHEA AND Brown at their own pace.
This is will give us the time to choose who is the best out of them and more time so that they can mature more.
Remember then with Blanc leaving next year we will only have 2 leaders. Rio and Gaz. And i cannot see Oshea- Brown leading our backline if the others get injured
