With a yellow fore-super, long pp and 4 emarginations….you might be hard pressed to turn this into nominate Chiffchaff.

Cheers

Given how similar /difficult this (barely diverged) species pair is, I'm really loath to commit. I think Ken has amazing eyes to be able to make a cogent wing formula from these pics
 
I suspect that if the photo was taken in May most would agree that it was an Iberian Chiffchaff. Any minor (apparent) anomalies could be disregarded as being within the known parameters of this taxon. Equally, on these images, it would take a brave birder to rule out Common Chiffchaff entirely. The evidence I've seen suggests that Iberian Chiffchaffs largely (or entirely) decamp from Spain & Portugal in winter and are replaced by Common Chiffchaff so the latter seems more likely.
