Could a change in Boubacar Kamara's role help solve Aston Villa's defensive problems?

Aston Villa have made some encouraging progress with their new signings this season, and I think there is plenty to be positive about when you look at the quality of the players who have come into the football club. However, one area that hasn't quite come together yet is the defensive side of the team, and Saturday's 2-2 draw with Brentford provided further evidence that Unai Emery still has some work to do in finding the right balance.
