Tottenham assistant manager Kevin Bond has blamed Spurs' poor defensive record this season on the loss of central defenders Ledley King and Jonathan Woodgate.
King's chronic knee problems are well-known to Premier League fans, whilst the defender has also suffered various muscular injuries this season.
Tottenham fans could be forgiven for forgetting about Woodgate, as the English defender has been out of action for a year with a persistent groin problem.
Despite a wonderful first half of the season, Spurs have kept just one Premier League clean sheet and Bond admitted that losing key defenders has been a major factor in the team's struggle to shut out their opponents.
"Ledley King and Jonathan Woodgate, they were just marvellous for Harry [Redknapp] the first year," Bond told talkSPORT.
"They played a lot of games, took us from the bottom of the league to the top reaches. They are fantastic players, I think any club would miss players of that quality.
"No disrespect to the players that have been involved, William Gallas, Younes Kaboul, Sebastien Bassong and Michael Dawson who have done fantastic."
However, Bond could not offer Spurs fans much good news on the pairs' injuries, admitting that Woodgate is not near to a return yet.
"Woody’s sort of coming back, he’s a long way away from where we want him to be but he’s coming back and it isn’t easy when the backbone of your side gets messed around."
Spurs have a reputation as come-back specialists this season - winning five Premier League games after concededing the first goal.
Bond praised the team's spirit but admits that they need to stop making things hard for themselves and start keeping clean sheets more regularly.
"I must say I think that’s a remarkable feat the fact that it’s five games that we’ve won from being behind.
"The downside of that, of course, is why are we going behind in the first place, we need to look at that.
“Credit where credit’s due though, the lads have shown a lot of resolve and a lot of character to come back to win games from losing positions.”
