United had to relegate Real Madrid's Gareth Bale to the second most expensive player on the planet to prise him away from Turin.

But the huge fee never crossed Giggs' mind when he watched Pogba against the Saints.

“The biggest compliment I can give him is that I was watching that game and watching Paul Pogba and I wasn't thinking of £89m,” added United's most decorated player and Louis van Gaal's former assistant.

“I was just thinking of a player enjoying himself and trying things and expressing himself and as the game went on.

“Yes sometimes things won't come off, but he's trying things and he's releasing himself, he's all over the pitch, he wants to get on the ball and it was a brilliant, brilliant performance when you take into consideration he's only trained for a week, the price tag and he's still only 23.

“If he keeps playing like that, like I said the price tag won't be mentioned.”
