Roy Hodgson's England players returned to the fold on Wednesday to prepare for Sunday's European Qualifier in Slovenia.
The Three Lions extended their unbeaten run to ten games with a 0-0 draw against Ireland in Dublin last weekend.
And while Hodgson was pleased with certain aspects of the game, he admits they must do better when they go into their next encounter on the road to France 2016 in four days' time.

"You always learn at every game at this level, I learnt quite a lot and I think the players learnt a lot," said Hodgson.
"We have learnt some lessons, most important is: When you set yourself high standards you have to match them. And when you don’t match them you have to deal with the disappointments.
"We can’t look for the minor positives, such as another game unbeaten or another clean sheet, we have set very high targets.
"This might sound boastful but we believe we are going to get to the Finals in 2016 and there will be some tough games there."
That will be something Hodgson will now address back on the training pitch in the coming days leading up to their important trip to Ljubljana - their final game of the season.
All 23 members of Hodgson's squad reported for duty at the team base after a two-day recuperation following the Ireland game.

And they will be keen to continue their perfect record this campaign with another victory that could, potentially, see them end the season nine points clear at the top of Group E.
The Three Lions beat Slovenia 3-1 in Group E before an 82,000 crowd at Wembley last November. Wayne Rooney, winning his 100th cap, scored one and Danny Welbeck grabbed the other two.
The clash at Stadion Stozice on Sunday will be only the fourth between the nations, which includes a meeting at the 2010 World Cup, and the first on Slovenian soil.
Slovenia currently lie joint-second in Group E, six points behind Hodgson's men, having won three matches and lost two. They have won both of their home fixtures with clean sheets.
