Harry Kane has admitted that England's failure at the European Championships might still be affecting the players' confidence.
The Tottenham Hotspur striker put on a lacklustre display in front of goal during the tournament as he failed to score.
Kane headed into the Euros as the Premier League's top-scorer with 25 goals, but he and the rest of the England team limped out at the last-16 stage to Iceland.
The Three Lions returned to competitive action on Sunday as they took on Slovakia in their opening 2018 World Cup qualifier, which was also Sam Allardyce's first match as England boss.
It took 64 minutes for the team to produce a shot on target, and they eventually sneaked a 1-0 win thanks to a 95th-minute strike from Adam Lallana.
When asked by reporters if England's lack of confidence in attacking areas is because the team are still feeling the effects of the Euros, Kane said: "It could be.
"It is difficult sometimes when teams like Slovakia drop off and make it very difficult to play through, you have to be very patient and make sure that ball is spot on every time or they will cut it out. It is all about that final pass, putting a bit more care into it, but like I said we played well and could have won two or three-nil.
"We were very patient, we limited them to very few chances, we created some good chances but maybe the final ball again, whether it was a cross or a through ball, could have been a little bit better, but we are getting better in every game and it is a really boost that we won and hopefully we can kick on now in the rest of the group games."
England's next qualifier is against Slovenia on October 11.
