The Ivorian striker was on the scoresheet as County romped to a 4-0 victory over the Cumbrians, with Jeff Hughes, Neal Bishop and Jamal Campbell-Ryce the other goalscorers, but he spared a thought for his friends in the Carlisle squad.
Zoko said: "I still look for Carlisle's results and it was emotional for me today to see my old mates. I still have good relationships with everybody and I never left because I didn't like Carlisle."
County manager Keith Curle admitted: "Francois was disappointed not to be playing from the start, but he needs to catch up having missed the pre-season with us."
County themselves came off the back of two home defeats and Curle said: "The best way to show disappointment is by your next performance and we got that today. I have got faith in the system we play and I am building for the future.
"This is a difficult place to come to and the mental approach had to be right. I earn my money when we get negative results and we did a lot of preparation work on the tactical side."
