Silent failure of Sprite.Create() ?

Hello,

I'm completely new to Unity, and I'm trying to create a sprite when loading a scene. Here is my code :

 PlayerSprite = new GameObject(playerID);
             Debug.Log(PlayerSprite);
             PlayerRenderer = PlayerSprite.AddComponent<SpriteRenderer>();
             PlayerTexture = Resources.Load<Texture2D>(data.PlayerTexture);
             PlayerRenderer.sprite = Sprite.Create(PlayerTexture, new Rect(0, 0, PlayerTexture.width, PlayerTexture.height), new Vector2(PlayerTexture.width / 2.0f, PlayerTexture.height / 2.0f), 100f);
             PlayerBody = PlayerSprite.AddComponent<Rigidbody2D>();
             PlayerCollider = PlayerSprite.AddComponent<BoxCollider2D>();

All the variables used are initialized/have appropriate values, and I don't get any warnings or errors during script compilation or at runtime. However, the sprite isn't displayed on screen and the inspector lists my object's spriteRenderer as having no sprite. The other components are properly created and some of them work properly ( ie the RigidBody reacts to user input).

I feel like I am missing something obvious, but I have no idea what. Could someone enlighten me ?

Thanks in advance.
