Arsenal striker Chamakh impressed by Spurs veteran Gallas
The pair clashed for the first time two weeks ago when Spurs came from two down to claim an astonishing 3-2 victory.
Chamakh said: "It's still hard to talk too much about who are the most difficult rival players because I haven't been here too long but, against Spurs, Gallas was a very complicated defender to play against.
"I knew before I arrived at the club that Arsenal and Spurs have an enormous rivalry, but now I have had direct experience and it was terrific to be involved.
"I still don't understand how Tottenham were able to get on top in the second half.
"Now Arsenal's players have promised the match at White Hart Lane will be special and the challenge for us is to repay them."
