Cannot properly access player position

I have been trying to make an enemy script that cause the enemy to move towards the player. As far as i know i'm accessing the player object properly but my position variable always returns 0,0 which i suspect is null. My enemy object always moves towards 0,0,0 below is my script please could you have a look and see what i'm doing wrong? I'm new so please try and explain why I'm wrong as well but if you don't have the time, thanks anyway :)

PS: My player object does have the tag "Player" on top level and has a transform attached

 using UnityEngine;
 using System.Collections;
 
 public class enemyControllerA : MonoBehaviour {
 
 
     public GameObject target;
     public float speed;
     Vector2 playerPos;
     void Start () {
         target = GameObject.FindWithTag ("Player");
     }
     
     // Update is called once per frame
     void Update () {
         playerPos = new Vector2(target.transform.position.x,target.transform.position.y);
         float step = speed * Time.deltaTime;
         transform.position = Vector2.MoveTowards (transform.position,playerPos,step);
         print (playerPos);//always returns 0,0?? why god why!!!!
 
     }
 }
