Manchester United rediscovered their scoring touch during the week against Newcastle United, but they certainly showed that they can concede them, too.
A big part of this is the injury problems they have at the back. Phil Jones was missing against the Magpies, and he will likely miss out again, while fellow defenders Marcos Rojo, Antonio Valencia and Luke Shaw are also on the sidelines.
Daley Blind is set to partner Chris smelling in the heart of the defence once again, while Ashley Young remains at right-back, despite being a winger by trade.
Bastian Schweinsteiger also missed out midweek, and he is not likely to be rushed back, meaning the central midfield will be patrolled by Michael Carrick and Morgan Schneiderlin.
Up front, United will be hoping that Wayne Rooney has finally got back to his best, and with Martial and Mata flanking him, the chances could come thick and fast.
Martial does not really enjoy playing out wide, but, after Rooney’s stunning double at Newcastle, the Frenchman – like Young – will have no choice but to play out of position again.
Some rumours leading up to the game are claiming that Red Devils boss Louis van Gaal will be given his marching orders should he fail to win, so there is more on the line than meets the eye.
