"There are quite a few lads who can really smash a ball," the goalkeeper told the club's official website.
"I'm just thankful that they do it on a weekend when it matters. The strikers for us have been fantastic. You can add Charles into that mix too. I think a lot of people forget that Christian is only 22. A lot of responsibility has been put on to his shoulders.
"He is such a big part of our team and he is not the only one. We know as a team we all have to help him and he has to help us and it is a collective unit."
Villa have scored 25 goals in 26 Premier League games.
