In leading Manchester United to 13 Premier League titles, Sir Alex Ferguson often underlined the importance of 1-0 wins.
It turns out that wins by such a slender margin are just as significant when it comes to securing a top-four place and Champions League football.
United may have last won the title a decade ago and remain some way from challenging for it again, but in terms of where they are now, this was a huge win in their quest for a top-four spot. It came courtesy of a first-half goal from skipper Bruno Fernandes, but there were heroic performances from so many in the famous red shirt, not least Casemiro and Victor Lindelof.
