Spurs, after defeat at home to Crystal Palace last, now sit just one point above the dropzone.
On TNT Sports, Crouch said: “I think since Christmas, in 2026 it’s proven that is the case, so yes is the honest answer.
“Wolves have picked up a little bit, you know bottom of the league. Teams around them, West Ham picking up points, Nottingham Forest.
“Spurs at the moment, form-wise, are without doubt are the worst in the league.”
Crouch, who played for the Spurs between 2009 and 2011, continued: “Palace were a better side for me before the game with 11 men, going player for player.
“There’s not many players I take from Tottenham’s team and put in Palace’s, and goes down to recruitment, it’s been poor for a couple of windows now.
“I look at the pitch now, and there’s a distinct lack of quality and lack of characters, and that combination can get you relegated.”
