Defeat at Stamford Bridge on Saturday leaves the Villains in 19th place.
Aston Villa came unstuck against an out-of-form Chelsea side on Saturday in what was their fifth league defeat in a row.
Sherwood has previously spoken about his desire to play an attractive, progressive style of football but Murphy feels they need to play to their strengths.
“There has been a lot of change there and that normally means you need some time… but I think he (Sherwood) has to alter his perception of how he wants his team to play,” he said on the ‘Alan Brazil Sports Breakfast Show’ on talkSPORT today (aired at 07:55).
“He’s got a monster of a striker who’s brilliant in the air and maybe they’ve got to be a bit more direct.
“I know he said he’d rather stick to his footballing principles but sometimes as a manager you need to adjust a little bit and they’ve got probably the best header of the ball in the Premier League - if it means you have to go a little bit more direct then so be it.”
A change of some sort is undoubtedly required at Villa Park after their poor start to the season and harnessing the aerial threat of Rudy Gestede seems like a sensible place to start.
The former Blackburn Rovers striker has quickly demonstrated his power in the air this season and could prove a potent weapon for Sherwood’s team, given the right service.
The former Spurs midfielder has become known for his stubbornness in his short time as a Premier League manager however and may well stick to his principles this season at the expense of Villa’s prospects.
