David Moyes will run the rule over West Ham target Joao Mario at the San Siro on Sunday night.
The Hammers boss has made a midfield signing his No.1 priority before the transfer window slams shut at the end of the month.
And the Scot will make a personal scouting mission to Italy to see the Portugal international in action for Inter Milan against Roma.
A host of clubs are interested in the 25-year-old, who has failed to live up to expectations after joining the Serie A giants for £38million from Sporting Lisbon 18 months ago.
Mirror Football understands that West Ham have reached an agreement to sign the midfielder from Inter on loan until the end of the season with a view to a permanent transfer.
But boss Moyes wants to see him first hand before making a final decision.
Speaking during his press conference ahead of the Hammers’ Premier League clash with Bournemouth, Moyes said of Mario: “He’s a good player, an interesting player.”
Moyes, 54, may also make a late swoop for a striker with West Ham ready to take a hit on selling Javier Hernandez.
The former Manchester United forward arrived last summer from Bauer Leverkusen for £17m but has struggled to make an impact. It is understood Turkish giants Besiktas are keen.
