Cole, who spent nine years with the Gunners, hopes that results like the 3-1 win at the London Stadium can propel Ljungberg into the permanent role.
“Freddie is there and hopefully he can take over as permanent manager - he knows the club inside out," Cole told Sky Sports.

The former England left back added, "Arsenal are in a transition period - they tried Emery and for whatever reason it didn't work out."
