With the soon-to-be Manchester United manager insisting that Daley Blind would play as a left-back, it appears that he has moved to a 3-4-3 formation with Wesley Sneijder and Giorginio Wijnaldum as a midfield two, backed up by Blind and Dirk Kuyt as wing-backs. Nigel de Jong is unavailable, but this is a totally unexpected change.
It's possible that Van Gaal might've been lying - it's possible the lineup could also be a 4-3-3 with Blind in midfield and Bruno Martins Indi at left-back. Memphis Depay, Robin van Persie and Arjen Robben appear to be the front three, but even that isn't certain, as there's some suggestion Depay could be one of the wingbacks.
No such shenanigans from Costa Rica however, who have gone with their expected lineup.
