Chelsea defender David Luiz is urging the club's youngsters to grab their chance in preseason.

With Mason Mount, Tammy Abraham, Fikayo Tomori playing key roles in the 4-0 win at St Patrick's Athletic in Dublin on Saturday, with 18-year-old Billy Gilmour impressing in the second half, Luiz is excited at the potential of youth at the club.

"When you're young you have to think about opening the door - not the door opening for you," said Luiz.

"The young players have to work in this mentality, because life is not easy.

"Every day another boy is born and another boy wants to be a footballer. And it's up to everybody to work hard and for them to knock on the door and open the door. They have the talent for that, they have the potential for that. They just have to show that every single day.

"I think we are a lucky team because we have so much talent, the young players are amazing. Every single one, they have the quality already to play for this club. I have to do my role as a senior player, just trying to help them. It is a big step up and it's up to everyone to do their job."
