Well Porto also won their league with him too lol. Not sure what else you want him to prove really. He's proven he can win on the biggest stages with small or large budgets. That's why I consider him the best maanager in the world.
The Portuguese League? Forgive me if I don't sent him a congratulatory telegram.
This is what I don't get. Best manager in the world for winning the Premiership with £300m? Oh yes, and the Champions League against Monaco, clearly better than Wenger.
We've gone slightly off on a tangent mind.
Souness couldn't win the Portuguese League
