Villa brought in a huge number of new players during the January transfer window, to try and add quality to their squad.
The claret and blues targeted some of the top performers in the Championship this season, with the likes of Scott Hogan, Conor Hourihane and Henri Lansbury all arriving at Villa Park last month.
However, Villa’s form has taken a turn for the worse since the start of the transfer window.
Villa have not won a match in 2017, and they were beaten 3-1 by Barnsley in front of their supporters last night.
And Bruce admits that he may have been too hasty to change things up at Villa Park.
“Maybe it’s been too quick to change three quarters of the team,” Bruce said. “That’s my responsibility, I take that on board. The buck stops with me, and I will do my utmost to turn it around.”
Villa are currently in 16th place in the Championship table, and they are now looking nervously over their shoulder.
The claret and blues are just seven points above the relegation zone, with their next match coming against Newcastle United at St. James’ Park.
