Lazio coach Maurizio Sarri says they must make the most of their chance in the Europa Conference League.
Lazio meet in the first-leg of a playoff wth CFR Cluj.
Sarri said, "Like any European competition, it must be respected and we will do that.
The league can give us access to more money and for a club that is important. If we talk about the sporting aspect, a European competition must interest us.
I will make my choices based on the tiredness of the players. I still don't know who will play in goal.
At European level all games come out tight, there are no games that are not tough. If we thought like that we would be sinning in superficiality.
To build a mentality takes years, three or four days are not enough. It is born in the everyday."
