The Three Lions captured the nation's attention with a string of positive performances, but suffered a 2-1 defeat to Croatia in the semi-finals of the competition on Wednesday night.
Despite failing to make the final, Charlton - who won the World Cup in 1966 - has insisted that England can be delighted with their showing in Russia.
The 80-year-old also insisted that the future is bright under current boss Gareth Southgate.
As a former @England player, I wanted to say how proud I am of what @GarethSouthgate and his team accomplished this @FIFAWorldCup. I'm sure the players will be disappointed not to have reached the final, but there is so much to be hopeful about for the future.— Sir Bobby Charlton (@SirBobby) July 12, 2018
Charlton scored 49 times in 106 appearances for the English national team between 1958 and 1970.
