With his side anchored in the bottom half of the table and without a league win since November 1, Mikel Arteta needed a response against Burnley on Sunday but saw Xhaka sent off and Pierre-Emerick Aubameyang score an own goal in a 1-0 loss.
Arsenal have now lost for consecutive home league games for the first time in 61 years as they lie in 15th place.
The Gunners were looking to work their way in front before Xhaka’s moment of madness saw him sent off just before the hour for grabbing Ashley Westwood by the throat.
Frimpong, an Arsenal fan, was unimpressed by what he saw but is offering solutions.
He tweeted: “Sell Xhaka and get me on a free.”
Then followed up with the more drastic: “Let’s dissolve Arsenal with immediate effect.”
Frimpong made six appearances for Arsenal behind leaving in 2014. He retired from played in 2019 due to injury.
