Arsenal legend Ian Wright says fans support, rather than January spending, will assist in turning around the club's fortunes.
Defeat to Manchester United on Sunday, which leaves The Gunners fifth in the Barclays Premier League - five points behind fourth placed Chelsea - has left many fans believing the club need to strengthen in the January transfer window.
The timing of the window has often forced managers into panic buying to assist their domestic fortunes, while Arsene Wenger endured a similar situation during the twilight of the summer transfer period, something Wright hopes the French boss takes heed of.
"I know some people are tearing their hair out after Wenger hinted he is unlikely to spend in the transfer window," Wright said.
"But even though the team needs strengthening — that's clear for anyone to see — rushing out next week and making some rash signing would not be the answer.
"This happened on August 31 last year and I'm not sure whether Arsenal really benefited.
"Mikel Arteta has done OK — while the jury is out on Per Mertesacker and Yossi Benayoun has not really been given a chance.
"So I wouldn't say they have all been amazing successes."
Wenger came under fire during Sunday's loss to United, with the substitution of Alex Oxlade-Chamberlain, who had help lay on Robin Van Persie's equaliser, for Andrey Arshavin, leading to a host of boos from the home faithful.
Wright hopes supporters can put their grievances from the weekend aside, and concentrate on getting behind the team.
"The jeering was a case of the locals making a big point to their manager," Wright added.
"These actions were totally understandable and sometimes it's not a bad thing for fans to voice their disapproval providing it's a one-off.
"But it's important for the negativity to end right now. And I'm confident Arsenal's fans will get behind the team and not turn on Wenger.
"He needs to get the best out of his team and not just rely on one or two players. And most importantly of all, despite that moment of raw emotion on Sunday, Wenger needs to know that all the fans are behind him and the team."
