Arsenal fans, get ready for an odd transfer rumour which has emerged over the past 24 hours.
Melgarejo has played 20 games in the Primera Liga for the table toppers this season, as well as being an ever-present in their Champions League campaign, and path to the Europa League Final.
Certainly the defender signed for £1.2 million last summer appears to be a very good prospect.
But here's catch number 1, Melgarejo is a left-back, a position where Arsenal seemingly do not require cover.
Catch number 2, is the source for the reports in both countries is none other than British website TribalFootball.
The website claims Arsene Wenger has "had the 22 year-old scouted extensively this year."
Their report is no more than a stub at three lines long, with no quotes, reference, or suggestion as to where the rumour came from; leaving us perplexed as to quite where it originated.
Melgarejo has a huge 30 million clause in his contract report Portuguese newspaper A Bola, which would hamper the Gunners attempts to sign him if they were interested because it would mean there is no onus on them to sell for any less as his contract runs until 2018.
And Melgarejo is not a defender who has recently played in midfield either, or at all at top European level which would only suggest if he was signed then his addition would see Kieran Gibbs or January addition Nacho Monreal moved into midfield, but there is not really any particular reason to do so, for buying a left-winger would make more sense.
The defender will be in action against Chelsea in the Europa League Final for Gunners fans to keep an eye on, but we wouldn't recommend getting too excited at the potential addition, seeing as strengthening at left-back is simply not a priority for Arsenal.
If Arsenal were linked with his Paraguayan Benfica compatriot, freescoring striker Oscar Cardozo then that would make more sense to us.
So despite our extensive doubts, with it probably unlikely to materialise into a deal, it is worth keeping an eye on this one to see if it develops into anything more substantial over the coming months, just in case.
Arsenal fans what do you think of the reports? Have they been fabricated or is their any truth?
