First of all, how it happened. Leading 2-1 at St Mary's - with both players already on target - Dele broke through on goal and was brought down by Nathan Redmond as he pulled the trigger. Referee Mike Dean pointed to the penalty spot, Redmond was sent off and Harry stepped up...
...only for his standing foot to slip, moving the ball slightly as he struck it - and as he was looking for power, the slightly elevated ball flew skywards, and kept flying.

It mattered little as later goals from Heung-Min Son and Dele's second secured a 4-1 win in a pressure game after all our rivals in the top six had won on Boxing Day or Tuesday.
Here is the pair's version of events after the final whistle at St Mary's.
Harry: "Well let’s start with the fact that Dele should have scored in the first place, so we shouldn’t be in this situation! Before the game I saw a new patch of grass on the penalty spot and when I stepped up to take it my left foot sunk into the floor and that put the ball on a tee. Obviously it went a mile over and the keeper went the wrong way as well, that makes it even worse. I’ve been on a good run of penalties, scored quite a few, so that’s disappointing. I sent the keeper the wrong way but put it in Row Z. I’m just happy we won and it didn’t matter in the end."
Dele: "I’ve heard Harry talk a lot about American Football so if there were any coaches watching that one I’m sure they’ll be looking at him for a kicker!
"Look, he’s a fantastic striker, he puts them away all the time in training and in the other games so you always back him to put them away and when he doesn’t it’s a surprise and that just shows the player he is – you never expect him to miss. Finally, I’ve got something on him!"

Dele then underlined the importance of the victory. "We’re on a good run and to have gone 1-0 down, it just shows the character we have and we’re looking to build on that and keep progressing. We’ll move onto the next game now and try to win that one."
Next up is a trip to Watford and an early 1.30pm kick-off on New Year's Day.
