Southampton manager Ronald Koeman is taking nothing for granted ahead of the second leg of their Europa League qualifier against Vitesse Arnhem.

The Saints have won the first leg 3-0 at St Mary's last week and will travel to Arnhem for the return fixture on Thursday.

Koeman said: "Football is sometimes strange and if you don't start with enough concentration, if you don't play with the same intensity in pressing the opponent, then it's possible that you get a difficult evening.

"But if we play at our level with the same concentration and the same intensity, the qualities make the difference.

"We have to respect the competition because we did a great season last year and we played for the Europa League over 38 games in the Premier League.

"It is a crazy thing to think about it, to throw everything away in the start of the Europa League legs. I don't like that.

"I'm a person who likes to win always and I hate losing."
