Sterling is definitely not getting carried away with the promising start and believes England will have to improve markedly if they are to go deep into the tournament.
“I think we could have kept the ball a bit better," Sterling explains. “I think we could have played out from the back a bit more because when you come up against the Frances and Spains, teams like that, we can't just give them back the ball because it will be a long time before we get the ball back.
“We've got to do what they are going to try and do to us, they are going to try and make us run.
“We have got to do that to teams and we are more than capable of doing that.
“I thought at times we could have played a little bit more, just kept the ball, kept them running, especially when it is a hot day and we have got the right players to do that.
“It is just my thoughts. We played a good Croatia side but if we go into the last 16 you come up against these top national teams that have players who enjoy keeping the ball."
