The goal of switching to 3-5-2 was to get crosses into the box for Rudy Gestede to attack.
The Villa Park outfit were beaten 1-0 at home by Stoke City in a continuation of poor form for the club in recent weeks.
Sherwood usually plays with a back four, but against the Potters opted to switch to a back three, with Alan Hutton and Jordan Amavi operating as wing-backs.
The former Tottenham boss has stated that the thinking behind the tactical tweak was to get more crosses into the opposition penalty box for towering striker Rudy Gestede to attack.
"We need to find ways to get crosses in the box to Rudy more than we have been, because at the moment he is our threat to score goals as he's proved over the last few weeks," The Birmingham Mail quote Sherwood as saying.
"But we didn't do that well enough in the first period. We got the ball out wide to Hutton and Amavi nowhere near enough so we changed it at half time to try to find a different way.
"I thought we took the game to them better in the second period but still never had that one person who could show that maverick ingredient to be able to do something very special. Unfortunately that was missing today.”
Gestede scored an impressive bullet header in the 3-2 defeat to Liverpool the week prior and it is evident to see that the powerhouse provides a real aerial threat if provided with quality service.
Villa find themselves in the bottom three after eight matches, with four defeats on the bounce meaning that Sherwood’s side remain on four points.
The Midlands outfit will travel to take on Chelsea at Stamford Bridge after the international break.
