MY ENEMY SCRIPT:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Enemy : MonoBehaviour {

// Public Variables

public float speed;
public GameObject effect;

// Private Variables

private Transform playerPos;
private Player player;
private Shake shake;

// Functions

private void Start()
{
	shake = GameObject.FindGameObjectWithTag("ScreenShake").GetComponent<Shake>();
	player = GameObject.FindGameObjectWithTag("Player").GetComponent<Player>();
	playerPos = GameObject.FindGameObjectWithTag("Player").transform;
}

private void Update()
{
	transform.position = Vector2.MoveTowards(transform.position, playerPos.position, speed * Time.deltaTime);
}

private void OnTriggerEnter2D(Collider2D other)
{
	if (other.CompareTag("Player"))
	{
		shake.CamShake();
		Instantiate(effect, transform.position, Quaternion.identity);
		player.health--;
		Destroy(gameObject);
	}

	if (other.CompareTag("Projectile"))
	{
		shake.CamShake();
		Instantiate(effect, transform.position, Quaternion.identity);
		Destroy(gameObject);
	}
}

}

try adding in update(not tested)

//vector from enemy to the player
vector3 _aux = playerPos.position - transform.position;

//creates quaternion
Quaternion quat = Quaternion.Euler(_aux);
transform.rotation = quaternion;
