Villa are currently 18th in the Premier League table, having only drawn with newly promoted Sunderland at the weekend, their first match back in the top flight.
The team's poor start to the season has led to frustration from Emery, who publicly criticized his players for a lack of control and dominance on the field.
Emery stated that his team was "lazy" and not playing to their potential, but Walcott thinks that the players may be feeling bored with the manager's tactics and decision-making.
Walcott, who played under Arsene Wenger for many years, suggested that a change in voice or the introduction of new players could be beneficial for the team.
Emery's tenure at Villa is under scrutiny, and if results don't improve, he may face the possibility of being replaced as the club looks for someone to lead them out of their current slump.
