With the match crucial for both their Champions League hopes, Wilder is expecting a fearsome contest at Bramall Lane.
"People have their opinions on who it has affected and who it hasn't, but from Spurs' point of view it has helped them and they will be raring to go on Thursday night," said Wilder.
"They've got two top strikers back. They've got one of the top strikers in Europe back playing for them so they are stronger.
"Spurs are a huge football club with a stellar squad and an incredible manager and they will see this game as one they should be winning, that's for sure - and rightly so from their point of view."
