Not completely solved it - there was one play against Chelsea where he lobbed his guy on the half way line, ran threw on goal and passed it straight to Cech. I do love Jay, though, he's brilliant, and only 23, so loads of time for him to refine his finishing.
Part of the problem is that he tries to shape on everything to use his right foot...there are times when a little poke with his left would be the better option. Has still been very good, but if he can gain enough confidence to use his left when played in, he'll finish more chances.
