23-year old Bulgarian winger Tonev and 22-year old Spanish left-back Luna both recently joined Villa from Lech Poznan and Sevilla respectively and Lambert has urged them to adjust to their new environment as soon as possible.
"Learning English is important for them," said Lambert. "Some have better English than others but I think it is important, first and foremost, that they learn the language on the football side.
"By that, I mean the terminology on a football pitch. I think they've got to learn that.
"If they do that and they start to converse with people, it will bring their game on quicker.
"It is a strange environment for all of the new guys. But they will hit the ground running and once they start to know each other's names and integrate with each other then they will not have a problem."
