He did really well, credit where it's due, always. But can we not fall foul of the short-termism that we often succumb to, as we have also seen him play very badly.
I would say there are signs that he is improving as a #2 with time, but he is not young, so there is no reason to just believe that this improvement will be linear and that he will continue to play like he did yesterday.
I have seen enough of him to think that, so long as there is even a shred of doubt about Emi's long-term future, we should be looking to sign another goalkeeper. Not as a top priority, but somewhere in the mix. Hopefully we're keeping an eye out for opportunities that we might not have anticipated.
