William Saliba believes Viktor Gyokeres's goals will end Arsenal's trophy drought.
Gunners head coach Mikel Arteta last week finally landed his desired striker as Gyokeres joined in a deal worth around £64million after two goal-laded seasons with Sporting in Portugal.
Gyokeres is set to make his debut against Tottenham this week as Arsenal conclude their pre-season tour of Asia, and has been spending his first days getting to know his team-mates.
Saliba already has experience playing against Gyokeres in last season's Champions League, and is confident the striker's goals will land Arsenal's first trophy in six years.
"We know how good he is, it's scary to play against him," Saliba told reporters. "Of course, I'm so happy to have him in my club and I'm sure that he will help us to win games and win trophies.
"[He is scary] because when you face a striker who scores goals, you have to be focused! But now he's in our team and he will score for us, so that's good.
"Every year is different. We have to learn from the last three seasons. Of course, we are lucky to have a chance to compete in the Premier League again to try to win.
"Our mindset is to win the Premier League and we will give everything from the first game. We have a lot of new players and they will hopefully help us to win this league."
