The Young Lions will then face Macedonia on Monday before playing their final group game against France on Thursday – and DaSilva is "100 per cent" confident that the side’s attackers can fire them to the Elite Round.
Speaking at the team hotel in Paphos, DaSilva told TheFA.com: "Our attacking threat is quite ruthless. When we get one-on-one chances we usually punish sides.
"With the likes of Chris Willock, we can cause any team problems. If we can get him on the ball in the final third, he is more than capable of doing something and winning the game for us.
"But not just Chrissy, we have Layton [Ndukwu] and Lucas [Nmecha] too - so 100 per cent we have a few match winners.
"We just need to ensure we create the chances for our attackers."
However, despite the attacking threat he believes the side possesses, DaSilva still knows the importance of a clean sheet.
"The main thing is that we don’t concede. We have to defend properly as a team, and as a defender, I’ll be doing my best to make sure we start right there."
The 16-year-old, who also represented his country at U16 level last season, joined up with his England team-mates last Sunday at St. George's Park before flying out to Cyprus on Wednesday.
And the former Luton Town youngster says a good bond within the camp is quickly developing.
"We’re all settled in and the mood is good," he added.
"We’ve been together nearly a week now, and we are all looking forward to the first game.
"They’re going to be right up for the game, so we need to ensure we match that. It’s important we get off to a good start and set the tone for the remaining games.
"There is still a bit to go as we get to know each other, but it is starting to come together now."
And when it comes to bonding within a football environment, DaSilva knows all about togetherness.
Jay is in the unique position of having his two brothers, Rio and Cole, alongside him at his club – and he admits the sibling rivalries keep him on his toes.
"My two brothers are twins, and I’m the oldest so that’s good," he explained.
"They keep me on my toes, and they’re after me – so I need to keep working hard to stay ahead of them.
"But it’s great to have all three of us at Chelsea. We’ve played together since we were young, so hopefully one day that will happen at senior level."
