Southampton manager Ronald Koeman hailed hat-trick hero Sadio Mane after their 6-1 thrashing of Aston Villa.

Koeman heaped praise on Mane after his record-breaking hat-trick kicked off an "amazing afternoon" against Aston Villa.

"It's not normal to score a hat-trick in two or three minutes, not in the Premier League, Holland or the worst league in the world," Koeman said of Mane.

"I speak a lot to Sadio because first of all an important thing for the player is he has to know what his best quality is and the rest of the players have to know what the best qualities of Sadio (are).

"Sometimes I have a discussion and say 'you sometimes go down too much when backing in. You need to make movements in the space and then you are so dangerous because nobody is so fast as you'.

"He is a scorer. If you go down or to the midfield you are a long way from the goal of the opponent and you have to use your qualities.

"Today he demonstrated what we expect from Sadio. He's a great player, a great run player in front.

"We know for some players it's the first season in the Premier League but you have to learn and still he's a young player and he can do much better than he did. I believe that."
