The last time Erik ten Hag visited Selhurst Park, he had just been confirmed as Manchester United's new, permanent manager.
Sat up in the stands, he likely recoiled as his soon-to-be squad laboured to a 1-0 defeat that would have seen then drop into Europa Conference League had West Ham managed to beat Brighton.
A lot has changed at Old Trafford since then – Edinson Cavani, Alex Telles and Hannibal Mejbri all started against the Eagles back in May – and Ten Hag deserves endless credit for orchestrating the club's turnaround in such a short space of time.
However, there are limits to the Red Devils' progress, and talk of United mounting a title challenge was dealt a double-blow on Wednesday as they returned to the scene last season's crime against football.
Not only did Michael Olise's stunning free-kick ensure their nine-match winning run came to an end, a second-half yellow card for Casemiro means he will miss this weekend's mammoth showdown with Arsenal.
In truth, the result was what United deserved. If not for some trademark heroics from David de Gea in goal, they could have lost the game. Bruno Fernandes – who scored his side's goal, finishing off Christian Eriksen's cutback – even admitted as much at full time.
But Ten Hag & Co. cannot afford to lick their wounds. If their fledgling title hopes are to become reality, a result this Sunday is essential.
