Aston Villa are already four points adrift from safety, meaning that they are playing catch-up in the Premier League table.
The Claret and Blues lost their last game 1-0 to Stoke City, and it leaves them four points adrift of safety, in 18th position in the Premier League table.
Villa have not won a match since the very first game of the season, when they beat Bournemouth, and Sherwood has warned his side that they must start getting points on board soon if they want to avoid a relegation fight.
“I’d rather be in the bottom three now with eight games gone and with a new squad than with eight games to go,” he said.
“But you will be in the bottom three with eight games to go if you don’t pick up points now. That’s why the clock is ticking.”
Villa's poor form stems from the volume of the changes they made this summer, with Sherwood bringing in 10 new outfield players.
The Villans lost the likes of Christian Benteke and Ron Vlaar at the end of last season, and they have replaced them with rather unproven talent.
Villa preferred to sign young players with little experience of playing in the Premier League, but their form so far has suggested that the gamble hasn't paid off.
It leaves Sherwood with a lot to rectify over the international break, with Villa's next game coming against Chelsea in two weeks' time.
