Erik ten Hag made his first changes approaching the hour mark in Manchester United's match against Real Sociedad on Thursday.
The electronic board was raised and it signalled that Victor Lindelof and Donny van de Beek were coming off the pitch, to be replaced by Scott McTominay and Marcus Rashford, which suggested there was an interesting tactical/formation change to come.
That was indeed the case, with Ten Hag playing Diogo Dalot, Lisandro Martinez and Luke Shaw in a back three, with Casemiro and McTominay protecting that backline in a double pivot, while Rashford was asked to play where Van de Beek had been.
