Robert Pires has predicted Arsenal's problems will take a long time to solve - as the players are still 'sick' from Unai Emery's reign. Freddie Ljungberg took interim charge for Arsenal's game against Norwich on Sunday after Emery sacked last week following a run of seven games without a win.
But Ljungberg's side were unable to end that miserable sequence, with the Gunners needing Pierre-Emerick Aubameyang to equalise twice in a 2-2 draw at Norwich.
Arsenal are searching for Emery's permanent successor, with Mikel Arteta and Brendan Rodgers the leading candidates, while the likes of Carlo Ancelotti, Patrick Vieira and even Mauricio Pochettino have also been touted.
But former Arsenal midfielder Pires says whoever comes in, there will be no quick fix for the Gunners, who are currently languishing seven points adrift of the top four.

"They are going to have to be patient but this is a little bit what has been happening since the start of the season.

When you are lacking confidence, you take less responsibility. You try fewer things.
"I think going forward things look very good, but defensively, and Freddie knows this, with Per (Mertesacker), a lot of work is required."
Arsenal must stop leaking goals, having conceded 21 in 14 Premier League games so far - which is one more than they have scored.
