Freddie Ljungberg accused his Arsenal players of being "scared" as defeat at home to Brighton condemned the Gunners to their worst run of form in over 42 years.
A 2-1 reverse at the Emirates Stadium means Arsenal have gone nine games without a win, a streak not matched since 1977.
Neal Maupay's late header sealed a deserved victory for the Seagulls, who had led through Adam Webster's first-half effort as Alexandre Lacazette temporarily levelled for the beleaguered hosts.
Ljungberg replaced Unai Emery on an interim basis after the Spaniard was sacked last week, but has so far been unable to address an alarming slide in form.
Brighton's second away win of the season lifted them above Aston Villa, West Ham and Bournemouth into 13th.
Potter added: "We showed great quality and great courage, so overall I'm delighted with the players. It's fantastic to get three points and play like we did.
"Given the quality up front they have, everything can change, but credit to the players, they managed the situation well, and there was a bit of quality from us as well.
"We've had a tough batch of games so it's nice to come away from home, win, and play well. It gives us a bit more confidence on the path to going somewhere."
