The quoted Robertson fee seemed stupidly low, but then again most at the time didn't think it was all that bad because 90% of this forum didn't even think he was good enough for us.
I don't see how he was worth so much more at that time. He'd played one premier league season and looked promising yet committed his fair share of howlers, one year left on his contract and we'd just been relegated. Keane was better than Maguire that season and had 3 or 4 years of contract and he went for what most people think Harry should have gone for.
The summer before Boro were trying to sign him for £5m - £8m and half this forum offered to drive him there themselves, because we had Junior who was clearly miles better.
