How to stop already started transition in the animator and run next animation immediatley

I'm new to Unity and I have a problem with animator.

I have a pretty simple scheme: 3 animations, Idle, Run and Attack, and 2 parameters: float RunSpeed and trigger Attack.

When my character is running and I press attack button I want the character to stop and play attack animation (character cannot attack while running).

But I have such problem: The character is running, then I release Running button and animator starts Run-Idle transition. Then I immediately press Attack button but animator first finishes transition and only after that it starts attacking animation. As a result there is a short delay between I press attack button and the beggining of attack animation.

I already tried to add transition between "Any State" node and Attack, but it did not help.

How can I discard already runned transition and start attacking animation immediately?
