Player Sliding forward when moving Horizontal

Not sure whats going on but I have a player who only can move Left/Right the code works fine but as my player moves it slides forward. Not sure whats going any help would be appericated.

 var touch = Input.GetTouch(0);
		     // left
			     if ( touch.phase  == TouchPhase.Began && touch.position.x < Screen.width/2)
			    	direction = Vector3(transform.position.x, 0, -90);
			     	player.transform.LookAt(transform.position +1*direction); //look the right way
			        player.transform.Translate(Vector3.forward * 3* Time.smoothDeltaTime);

I think you need transform.forward instead of Vector3.forward inside your Translate to move the player in the direction it is facing. Like:

player.transform.Translate(transform.forward * 3* Time.smoothDeltaTime);
