I empathise with you. I had the same problem. But my manager was felt hreatened by me as he knew I was much better than him. One day I decided thts it. Just resigned and moved out of Qatar. I immediately got an offer from athe competitor but my previous employer cancelled my visa. I dont give a monkeys f..k as I have already got thee jobs and moving to one of them. So the point is if you are confident in what you do just pack up and leave and things will fall into place.
