Spurs have signed highly-rated Wales international Chris Gunter, while they made a bid Rangers star Alan Hutton only for the player to decide to stay at Ibrox.
The move for the duo has fuelled speculation over Chimbonda's long-term future at White Hart Lane.
"I am shocked that the club have made offers for two right-backs," Chimbonda told skysports.com
"I realise they have signed an exciting new defender in Gunter and also made a bid for Alan Hutton.
"I am essentially a right-back and although I don't mind playing in central defence to help out my team my proper position is right back.
"When I asked why the club had signed a new right-back and moved for another one I was told they wanted me to play in central defence and I just laughed."
Chimbonda's agent Willie McKay admits the player has found it difficult that the club are pursuing new full-backs.
"It is difficult that Tottenham are looking at players who play in Pascal's position," McKay told skysports.com.
"Pascal has proved he is one of the best full-backs in the Premier League and he could play for one of the top four clubs."
