West Ham have negotiated a £39million transfer clause included in the loan deal for loanee Joao Mario after securing his services from Inter Milan, according to a club insider.
Twitter account ExWHUemployee, who has established themselves as a reputable source of inside information surrounding the club, has revealed that the Hammers have seen an option included in the midfielder’s deal to turn the 25-year-old’s temporary move permanent, after confirming his capture via their official Twitter account on Friday.


The mega-money deal would mean that the Hammers could capture the 31-cap Portugal international for a record-breaking fee, with their current top spend the £25million spent on securing the signing of Marko Arnautovic last summer.
Mario has made 15 appearances for Inter this season, just six coming in the starting XI, and joined the Italian giants from Portuguese side Sporting in 2016.
Football Insider verdict
Any hopes of the Hammers making this move a permanent move have just taken a major blow with such a high clause included in the deal. Unless Mario tears the Premier League apart during his six month spell at the London Stadium, there is no chance the club are going to commit such a vast amount of money on the midfielder, and there should be questions asked over why negotiators allowed such a large value to be included in the first place. Still, this should not detract from the fact West Ham have secured an exciting loan signing for the second half of the season, which should certainly help in their hopes of securing their top flight safety.
