Gareth Southgate says England must convince themselves the run to the semi-finals of the World Cup during the summer was not a one-off.
The Three Lions created a buzz for supporters at home as they reached the final four of a major tournament for the first time since Euro 96.
Southgate’s men matched the achievements of Sir Bobby Robson’s 1990 squad, and their efforts will be acknowledged by a sell-out crowd at Wembley.
Harry Kane is also set to be presented with the Golden Boot before the Nations League clash with Spain.
Southgate, though, insists his England side cannot afford to bask in the afterglow of Russia for long.
“We’ve got to convince ourselves it wasn’t a one-off,” Southgate said.
“That’s the most important thing. That was a moment in time and it’ll be a summer (to remember).”
He added: “Our focus has to be how we get better.
“We need to get better to be able to compete at the highest level, with the best teams.”
