Mexican side Pachuca have confirmed they still own 30% of Enner Valencia's economic rights.
West Ham United lost a friendly against New Zealand based A-League side Wellington Phoenix yesterday - a poor performance only helped by Mauro Zarate's late consolation in the 2-1 defeat.
Zarate is just one of two South American strikers to arrive at the club this summer, as they have also agreed a deal to sign Enner Valencia from Mexican side Pachuca - for around £12 million.
The bullish striker put in some incredible performances for Ecuador at this summer's World Cup and is certainly a man in rich goalscoring form. Strong, fast and powerful he is a real Sam Allardyce player - and has the raw potential to become one of the Premier League's surprise packages of 2014-15.
But he did not feature against Phoenix yesterday. unfortunately he has not yet received a Work Permit and therefore was ineligible for the fixture.
That has now been confirmed by Pachuca themselves, with vice-president Andres Fassi declaring it only a week or so away from full completion.
But he also revealed something else in his press conference, confirming he had got his wish regarding the sale of Valencia.
When the deal was first discussed the Mexican side stated, via their chairman Jesus Martinez, that they wished to keep hold of some of Valencia's economic rights:
"We are seeking the possibility that is convenient for him and the club and that he is sold for the price that we like. We want to keep a percentage of the player in case he is sold in the future to another big team in Europe."
And Fassi has now confirmed that the club retain 30% of his rights, should The Hammers sell him on.
"We expect to finally give the visa to Enner to certify that he can go to West Ham. The English club made the necessary requirements and in six to seven days it will be resolved. It was a good deal for Enner, for Pachuca and for West Ham. We have faith in what he can achieve and that is why we retained 30 percent of his services."
That of course means that should West Ham sell him on in the future 30% of that fee will go into the coffers at the Mexican outfit. Even more reason for him to be a hit, as should he flop, West Ham would have to take a huge financial hit on the talented - but unproven - Ecuadorian.
