Can't change variable in script cia "GameObject.Find" (C#)

I’m a begginer in scripting (I’m write in C#) and I’m making a scene in which there is a spawning manager which controls enemy population and when it drops below maximum, it spawns new enemies over time. Now what I need to do is to write a script which will be attached to enemies and decrease variable of population by one when enemy dies, but I can’t figure out how to do this. My testing script looks like this:

public class EnemyScript : MonoBehaviour {
	public float hp = 100f;
	public Component ManagerSript;
		void Start ()
		ManagerSript = GameObject.Find("SpawningManager").GetComponent<ScriptAttachedToManager>();
		void Update ()
		if (hp < 0){
			//Other dying stuff

			//Here I want to decrease float variable called "EnemyCount" in script attached to the manager, when I delete this line there are no errors

But when I save this script I get this error:
Assets/EnemyScript.cs(22,38): error CS1061: Type UnityEngine.Component' does not contain a definition for EnemyCount’ and no extension method EnemyCount' of type UnityEngine.Component’ could be found (are you missing a using directive or an assembly reference?)
Also, without the last line there are no errors. I have no idea what is wrong here. Please, help me.

Use the actual type (which is the name of the script), not Component.
