The Three Lions are preparing for their tournament opener against Croatia this weekend and Rashford says that every single member of the squad has enough quality to make an impact at the finals.
The Manchester United forward said: "Don't get me wrong, everybody wants to be in the first XI - but I think from my experience of being in tournaments you need a squad.
"You have to have players capable of coming on at different moments and giving that extra spark. I think in our squad we have that all over the pitch, so to be honest it (starting against Croatia) is not at the front of my mind.
"We go there as a squad that's trying to win a tournament. Whether or not you're starting in the first XI you've still got a massive role to play if we want to win the tournament.
"You're being deluded if you expect 11 players to win seven games - and you're playing games in a short space of time. The squad's going have to be utilised and to be honest I'm excited and looking forward to it."
Rashford believes that the England squad has the ideal mix of youth and experience to cope with the pressure of tournament football.
He said: "We have a lot of young talented players.
"Then a mix with a few older players who've played massive games for their clubs and have ultimately had a brilliant career internationally. I think we've got a good balance.
"The first XI is important but not the be-all and end-all because we're going to need everyone to win a trophy."
