Tottenham manager Harry Redknapp has defensive concerns over Jonathan Woodgate and Ledley King.
The Spurs boss has revealed that both central defenders are struggling with injuries and that Woodgate will certainly miss the start of the season.
The 30-year-old centre-half has been dogged by injuries in recent years and only made three appearances for Tottenham last term.
He has not travelled with the squad for their tour of the United States and now faces a struggle to break into the first-team squad.
King, meanwhile, has long-term knee problems and after featuring for England in the World Cup, is also having fitness difficulties.
"Jonathan will not be fit for the start of the season," Redknapp said.
"He's in a position where he can't train or kick a ball.
"Ledley has come back and his knee is not great and he has a groin problem."
On the Tottenham squad as a whole, Redknapp added: "We have got a big squad, but having one or two new faces freshens everything up, and gives you a little push - and I think we need to do that.
"I do not think you have to spend big money in our situation. There are one or two players out there, whether it be loans or free transfers.
"You do not have to spend fortunes, but there are one or two players who would improve us."
Spurs kick-off their Premier League campaign against Manchester City on 14th August, the side they pipped to fourth spot last term, ensuring they finished in the UEFA Champions League places.
However, despite Tottenham's superior league standing, Redknapp believes it is only a matter of time before the Blues secure a top-flight title.
"They can go out and sign almost anybody," he added.
"They have come over here to New York and have almost 80 people in their party - it is just incredible.
"Money seems to be no problem, because the man who owns the club has so much.
"I genuinely think that eventually they will win the championship.
"If they continue and the owner stays involved, and he seems very keen, then I can see them in the next few years putting together a team that will win the Premier League."
