We're not really going to sign "great strikers" ever, January or July.
They might become great while they are with us (Like Lambert - although in fairness he was a great striker at the level we were at, he says arguing with his own point, but we were the big dogs then, we're not now). But J-Rod, Mane, Pelle, Mayuka, Osvaldo, Tanadari Lee - all gambles to an extent. As will the next one be.
The strikers we sign will only prove themselves to be great once we have them.
It's not looking likely Ronald is going for a striker this month but he's full of surprises.
If anyone can surprise us, Ronald can.
