Ferguson said: “I kept saying to people: ‘Will somebody please shoot Drogba?’ because his performances were unbelievable.
“He carried their team, I thought, and he kept getting these incredible goals. Like the one at Everton with the last kick of the ball. That was incredible.
“I thought he may win the title on his own at one point, but the drawback for them was that he had to play all the games because they couldn’t leave him out.
“I remember us watching Drogba before they bought him. But the price was about £25million.
“That was a lot at the time. He had only had one season at Marseille. But they took the risk and paid for him. He is a powerful lad, a massive physique. He has strength and plays every game.”
