How Do I Instantiate An Object Behind My Character

Hey guys, I'm doing a 2D Platformer and I have a sword slash animation that I want to instantiate behind (Z position) my character instead of in front.

Right now it works, just it's in front of my character. Can anyone help me please?

The main file:

using UnityEngine; using System.Collections;

public class Slash : MonoBehaviour {

 private float nextShotTime;
 public Object Sword;
 //public GUITexture moveFire;
 private const float fireInterval = 0.3f;
 
 void Start (){
     nextShotTime=Time.time;
 }
 
 // Update is called once per frame
 void Update () {
     
     if (Input.GetKeyDown(KeyCode.Y)) {
         nextShotTime = Time.time+fireInterval;
         if (GameObject.FindWithTag("Player"))
         {
             GameObject go = GameObject.FindWithTag("Player");
             Vector3 newPos = new Vector3(1f,0.0f,0.0f);
             newPos = go.transform.TransformPoint(newPos);
             
             GameObject projectile = Instantiate(Sword, go.transform.position, go.transform.rotation) as GameObject;
             Physics.IgnoreCollision(projectile.collider, go.collider);
             Rigidbody rb = (Rigidbody)projectile.GetComponent("Rigidbody");
             rb.velocity = go.transform.TransformDirection(Vector3.left) * 0;
         }
     }
 }

}

The lifetime manager:

using UnityEngine; using System.Collections;

public class SlashScript : MonoBehaviour {

 private float endOfLife;
 public float lifeTime = 0.01f;
 
 // Use this for initialization
 void Start () {
     endOfLife = Time.time + lifeTime;
 }
 
 // Update is called once per frame
 void Update () {
     if (Time.time>endOfLife)
         Destroy(this.gameObject);
 }
 void OnCollisionEnter()
 {
     Destroy(gameObject);
 }

}
