Sturridge told Sky Sports News: "I was pleased [to score] but it's all part of the preparation. It's about the team, it's about the tactics that we're going to be playing in the future, it's about everybody gelling together, and it's all about the preparation as I say.
"We'll take the positives out but we move forward. I'm looking forward to the World Cup, being part of the squad, it's about the team, not about myself.
"[Playing in the World Cup] is the pinnacle of everyone's careers and I can't wait to get there."
England will now fly out to Miami for warm-up games against Ecuador and Honduras on June 7 and 10, before they leave for Brazil.
