The Gunners opened the scoring in Sunday’s North London derby before they were humbled by Jose Mourinho’s men.
Frimpong who played for the Gunners between 2011 and 2014 after developing through their youth ranks, bemoaned the defensive blunder made by David Luiz and Sead Kolasinac which paved way for Spurs’ equaliser on Sunday.
Alexandre Lacazette’s stunning strike broke the deadlock at the Tottenham Hotspur Stadium in the 16th minute but the lead was cut short after Luiz failed to clear a back pass from Kolasinac 137 seconds later.
The blunder which led to the equaliser got Frimpong disappointed, and he tagged it as ‘shocking defending’ between Luiz and Kolasinac.
“What the hell. What’ going on? This is what I was telling you before,” Frimpong was quoted as saying by HITC.
“The defending is shocking. Shocking defending. Shocking defending for professional footballers.
“Shocking, David Luiz and Kolasinac. Shocking. I mean this is what it feels like to be an Arsenal fan. One minute you are happy and the next minute you are sad. It is what it is.”
Frimpong retired from football at the age of 27 in March 2019 after struggling with recurring knee problems.
