Tottenham boss Harry Redknapp has rapped the club's summer signings.
"The club have paid a lot of money for these players because they are supposed to be quality players but they need to show that on the pitch," he said.
"We have some players in there who need to do a lot better than they are at the moment."
Asked if he had plans to bring in replacements, Redknapp replied: "I haven't got anyone in mind.
"It is pretty quiet really. Where do you find good players this time of year? It is hard."
