Arsenal legend Tony Adams is shocked by manager Arsene Wenger's reluctance to compete in the transfer market. Only Yaya Sanogo and Mathieu Flamini have been signed by Wenger on free transfers this summer.
Adams told the Mirror: There's not going to be a lot in it on Sunday.
"Tottenham have spent a lot of money, they have got better and Arsenal have not been challenging for trophies while too many big players have walked out of the door, which has been galling for the supporters.
"Tottenham have come back to Arsenal in recent years and north London derbies have certainly changed a lot since my first one, when Stewart Robson kicked Glenn Hoddle all over the pitch and we could have a good fight.
"I'm also critical of Arsene for selling Robin van Persie.
"Once you have got that type of player, you should give him the world to keep him. But Robin chose to join a club who are challenging for the title every year where Arsenal are now challenging to finish in the top four.
"I admire Arsene for sticking to his principles, but somewhere along the line you have to win trophies as well. It's easy to criticise from this side of the fence, but Arsene didn't do enough to keep Van Persie."
