Liverpool ace Luis Diaz says his tough upbringing drives him during games.

Diaz, watched from the stands by his younger brother Jesus, was in tears at the final whistle of Liverpool's 3-2 Champions League semi-final second-leg win over Villarreal after coming off the bench at half-time to put in a man-of-the-match performance and secure a 5-2 aggregate victory on Tuesday evening.

Asked where he got his self-belief from, Diaz told UEFA's YouTube channel: “From La Guajira. It comes from my roots. I always played football in my town, in my homeland.

“They are my characteristics, they have instilled in me several things that I have today and now I have grown much more. That's my game.

“Each game is a revenge for always going out to look for more, I know what it costs and I have to take advantage of every moment, every minute I have.

“The rest is very important for what is to come.

“I'm very happy and glad what is happening, of course. I'm going to play in a Champions League final, it's like I always dreamt.

“The most important thing was that I managed to help the team.

“In the second half we all did well, the players that came on helped as well and supported us in order to get the result.

“That was really important, so I'm content and happy with all that went on."
