When will Isagi start missing?

In all the time in the manga, isagi has never missed his direct shot. Despite the fact that he hits on the fly and this is the most difficult and unpredictable type of shooting. The ball hits the wrong place a little bit and that's it - the hit flies not into the goal, but into the sky. But isagi has no problems with this, whether he strikes with his right or left foot.

Even players like Barou, Rin or Kaiser do not have 100% accuracy, although their shooting parameter is higher than isagi's.

The question is, when will Isagi start missing shots on goal ?
