Gareth Southgate’s side secured their place at next year’s showpiece in Russia with a 1-0 defeat of Slovenia at Wembley on Thursday courtesy of a late goal from captain Harry Kane.
England have now not lost in 20 qualifiers but Southgate says there is much improvement needed from a side he feels are playing well below their true potential.
And the Three Lions boss has called upon the nation’s supporters to continue to back his evolving side.
He explained: “As a young team, what they are having to deal with in terms of expectation and criticism of their performances, it is tough for them.
“They are young players we have to try to get behind.
“They are giving absolutely everything they have got. They don’t have Champions League-winning medals throughout this group, they don’t have Premier League-winning medals. They are a work in progress.
“But they will give everything they’ve got for the shirt and they are going to improve over the next few years. They are suffering a little bit from the consequence of the last 25 or 30 years. That isn’t their fault so we have to give them the belief and the backing to achieve.”
He added: “It is important we stay together as a squad. We will not be releasing players.
“There will be England fans travelling to Lithuania and we owe it to them to put in a performance.”
