You should just give up. What a trash post. He's "Lucky" every fucking week to you people.
I can easily give up Your Almighty, but it will not mean you understand more about this game. The "trash" is the anger on your behalf and lack of objective thinking in this case.
You are looking at the mere result of the goalkeeper's decisive saves yesterday, but yes, SOME of his great saves were LUCKY - as I've stated, as some great saves always depend on pure luck. To see that all you need is the eye of a coach, or an unbiased player, even an unbiased spectator.
When a GK throws his body in the way of an incoming player or shot, his intention is to cover the maximum angle. The larger his body is, the more chances he has. When the shot finally finds his toe, tip of finger, ear or any bodily part for that matter, he plays a kind of "russian roulette" which sometimes works, sometime it does not.
When the otherwise conscious move stops the ball, it's a great and expected result but it is considered by ALL pro footballers something that NEEDS LUCK, besides the skills (which lead to him throwing his body in the trajectory of the ball) and intentions.
BTW, he is NOT "just lucky every week" (minus the unnecessary and emotional f....ing word) because he is a very good goalkeeper, but sometimes he IS LUCKY, as all GKs are and need a bit of LUCK to be effective.
He had a fortunately very good game yesterday (apart from the goal conceded), but all GKs need a drop of luck.
He will become not only a very good but a great GK when he is also able to save much easier balls as well.
