People Jack may not be a Shaka, or a Ince, but I do not know what Mexico game alyuh see but the one that I saw had Jack making two or three errors but pulling off a few big time saves too. Which world class keeper does not make errors, football is a game of errors (although we must seek to minimize them).
Both Shaka and Ince have been guilty in the pass of making a few error as well, so let us be fair to Jack. I know he aint 100 % polished as yet, but at this moment he is all that we have, so instead ah calling for men who have other priorities at the moment (professional, personal, or injury), we need to build the man confidence not call for his replacement, we are supporters too, not only critics.
I am certain the technical staff have noted his faux-pas and will be working with him to correct them.
Hey, let us not forget that it had 10 other men who coulda stop the Mexicans before they reach up on the goal line to score both goals.
