Player not rotating with camera

Hey, so I was writing a mouse look and player movement script to replace the one that comes with unity, but for some reason, the character rotation is not working.

MuseLook Script :

 using UnityEngine;
 using System.Collections;
 
 public class MouseLook : MonoBehaviour {
     private float lookSensitivity = 5f;
     private float xRotation;
     private float yRotation;
     private float currentXRotation;
     private float currentYRotation;
     private float xRotationV;
     private float yRotationV;
     private float smoothnessFactor = .1f;
     CursorLockMode wantedMode;
 
     // Use this for initialization
     void Start () {
         wantedMode = CursorLockMode.Confined;    
     }
 
     public float returnXRot () {
         return currentXRotation;
     }
 
 
     public float returnYRot () {
         return currentYRotation;
     }
     
     // Update is called once per frame
     void Update () {
         Cursor.lockState = wantedMode;
 
         xRotation -= Input.GetAxis ("Mouse Y") * lookSensitivity;
         yRotation += Input.GetAxis ("Mouse X") * lookSensitivity;
     
         xRotation = Mathf.Clamp (xRotation, -90, 90);
 
         currentXRotation = Mathf.SmoothDamp (currentXRotation, xRotation, ref xRotationV, smoothnessFactor);
         currentYRotation = Mathf.SmoothDamp (currentXRotation, yRotation, ref yRotationV, smoothnessFactor);
 
         transform.rotation = Quaternion.Euler (currentXRotation, currentYRotation, 0);
     }
 
 }

PlayerMovement Script:

 using UnityEngine;
 using System.Collections;
 
 public class PlayerMovement : MonoBehaviour {
     private float speed = 10f;
     private float jumpForce = 8f;
     private float gravity = 30f;
     private Vector3 moveDir = Vector3.zero;
     public GameObject playerCamera;
 
 
     void Start () {
         playerCamera = GameObject.Find ("playerCamera");
 
     }
 
     void Update () {
         CharacterController controller = gameObject.GetComponent<CharacterController> ();
 
         if (controller.isGrounded) {
             moveDir = new Vector3 (Input.GetAxis ("Horizontal"), 0, Input.GetAxis ("Vertical"));
             moveDir = transform.TransformDirection (moveDir);
             moveDir *= speed;
             if (Input.GetButtonDown ("Jump")) {
                 moveDir.y = jumpForce;
             }
         }
 
 
         moveDir.y -= gravity * Time.deltaTime;
         controller.Move (moveDir * Time.deltaTime);
 
         transform.rotation = Quaternion.Euler (0, playerCamera.transform.rotation.y, 0);
     }
 }
 

Any help would be much apreciated
