Christian Eriksen's superb late winner gave Tottenham Hotspur a win over Crystal Palace, keeping them in the title race and cutting Chelsea's lead to four points.
But this was not in any way a convincing performance. Palace were by far the better side in the first half, dominating midfield, and though they could not create much in the way of chances, Spurs still looked iffy at the back and generally abject everywhere else.
At half-time, Mauricio Pochettino took off Victor Wanyama before he got himself sent-off - he was lucky to escape a second yellow card for a second late tackle - and the injured Mousa Dembele. On in their stead came Son Heung-min and Moussa Sissoko and immediately Spurs were better, though not immediately dangerous.
The turning point came on 53 minutes when Harry Kane beat Mamadou Sakho to a bouncing ball, powered away, and Sakho's studs caught in the turf as it tried to retrieve the situation. After a few minutes of treatment, he was sadly stretchered off, and by the look of things, will not be seen again this season - at least.
Even then, Spurs, for all their possession, did not fashion many scoring opportunities, even though they always seemed likely to find a way. And they did, Eriksen taking a pass from Kane on 78 minutes to stroke a beautiful low finish into the far corner.
So to the weekend, when Chelsea visit Everton and Arsenal visit White Hart Lane. If the gap is still four points on Sunday night, Spurs' challenge will be close to over, but for the leaders, the pressure is now on.
What does Moussa Sissoko do? Brought on at half-time, he did more or less nothing but accidentally foul more skilful players after they'd befuddled him with pace and trickery. But, in the final seconds, all was revealed: his ability to keep the ball in the corner is exceptional. Finally, we understand.
