Walsall manager Dean Smith will replace some of his players after a lucky 2-2 draw with Scunthorpe at the Banks's Stadium.
Although the visitors did not equalise until the fourth and final minute of stoppage time in Saturday's League One encounter, when substitute Jimmy Ryan rammed home a low drive, they were by far the better side.
A puzzled Smith said: "They (Scunthorpe) were the better team by far and we were poor. I told the lads I am not going to start ranting and raving about it, but I will make them watch it back.
"We stopped a three-match losing run, and that's all we did. We didn't play well enough to win and made basic errors all over the pitch.
"If players don't perform they will leave the football club and I will bring in somebody else who can - simple as that. The only thing that lifted us was Will Grigg's goal - you won't see a better one anywhere in the country."
