Les Bleus came from behind to beat Gareth Southgate's side in Paris, despite having to play almost half of the match with 10 men after Raphael Varane was sent off in the opening minutes of the second half.
Even with their numerical disadvantage France's youthful side looked like the better team, but Lloris stressed that there are still improvements to be made if they are to fulfil their potential.
"We can be very proud of our performance, especially in the second half, with 10 men," he told reporters.
"But we need to improve as a team, because when there is pressure in an important game, we need to be able to get the possession of the ball better, to be stronger too and to manage the rhythm of the game.
"Talent is not enough. You need to work, to work hard as a team, individually too, especially at this level."
France currently sit second in their World Cup qualifying group and as things stand would need a playoff to reach next summer's tournament in Russia.
