Why didn’t Sri Krishn and Arjun form the Chakravyuh first to capture Dhuryodhan?

At the time of war Dhristadhumn was the commander in cheif. There is no mention if he had any knowledge of such form of war. Even if the Chakravyuh was formed then Pitama Bhishm and Drona knew how to break the Chakravyuh formation. So there was no logical reason to make such formation in the war. The Pandavs were out numbered so they mainly formed defensive strategy to tackle the opposition.
