England manager Roy Hodgson believes his squad is still evolving and will continue to improve ahead of Euro 2016.
The Three Lions are aiming to maintain their 100 per cent record in their European Qualifiers when they take on Slovenia on Sunday.
Hodgson and his captain Wayne Rooney spoke to the press in Ljubljana shortly after arriving ahead of the big game.

The pair then headed out to the pitch at Stadion Stozice where they will play their final match of the season.
All 23 members of the squad trained in the warm conditions at the 16,000-seater venue, which is home to Slovenian outfit Olimpija Ljubljana.
But the group featured a number of different faces to the squad which trained in Manaus ahead of their World Cup opener in Brazil, exactly a year earlier. And Hodgson is pleased with how his team has developed over the past 12 months.
"It's a very different team to the team we had a year ago," Hodgson told the press.
"I believe it's an exciting team and a team with a large margin of progression.
"It's a team that will grow and will get better and I, as a coach, have got to be satisfied on their behalf that it is a season unbeaten before the final game."
Hodgson and Rooney speak to the press
He continued: "Seven wins and two draws - that's got to be worth something because we're in the business to try and win matches.
"You can only play the opponents that are put in front of you and we've beaten seven and drawn with two.
"Everything is there to be improved. We need the experience, we need the work, we need the games and all the challenges that will come our way during the next year.
"Our aim as coaches will be to try and help the players deal with those challenges and help them deal with all the things that happen in their footballing lives so that in a year's time we'll be one year stronger."
England go into the game at the top of Group E, six points clear of the Slovenians, who are in joint-second spot are level with Switzerland.
When the sides met at Wembley in November it took nearly an hour for Hodgson's men to find the net - through a Rooney penalty - but that was only after Jordan Henderson's own goal had sparked them to life.
The game finished 3-1 to England, but will also be remembered as Rooney's 100th international appearance.
And as he narrows in on another record - he is two shy of Sir Bobby Charlton's 49 goals - the Manchester United man is only focused on picking up three points.
“That's the way it's been over my whole career," said the skipper. "The team comes before I do.
"I want to try and win with the team and be successful with the team. If I can do well too, then great. But first and foremost I want the team to win.”
He added: “It would be great for us to go the whole season unbeaten, a great achievement. We've played some great football in that time, some very good results, and we have to maintain that on Sunday night.
"The training's been good, we've worked hard and how we want to play the game, the lads are focused and ready for a big game.
"We're ready to win the game in the 90th minute if we need to.”
