Last season’s top scorer Nugent netted the Foxes second goal of the game from the spot, pulling the result back to 3-2, before Ulloa rounded off the memorable victory with the fifth inside the final 10 minutes.
The 29-year-old scored nine of his 12 attempted penalties last season, and he opening his Premier League goalscoring account with his first attempted spot-kick of this campaign.
Praise has been heaped on the Foxes for their incredible performance in the match, but there is no denying that the two penalties certainly helped them in their cause - and Nugent has revealed that he even had help when it came to converting the spot-kicks.
Speaking to the official Foxes website after the game, the once-capped England international said: “I knew at 3-1 it was vital that I scored to get us back in the game. I watched clips on De Gea and his penalties last year, like when Steven Gerrard had three penalties against him.
“He seems to like to wait until the last minute, but he always dives, so I knew if I put it down the middle he was going to go one way.
“I think for the second penalty he was a bit wary of Leo going down the middle so he didn’t move until the very end and it was a good penalty.
“You practice these things in training and it paid off.”
However, it wasn’t just practising that helped Nugent and Ulloa finish their chances - technology plays just as an important part in modern day football as on-pitch experience.
“It’s all on the laptops and the iPads we get at the training ground – which way he dives, which ones he’s saved, which is his favourite side, which ones he missed.
"We’ve got all the information; it’s just up to us now to put it into practice on the pitch.”
It has become a common occurrence to see goalkeepers watching videos of penalties immediately prior to the start of a shoot-out, and it certainly raises the stakes to have the takers observing goalkeeping tendencies as well. Whilst there may be complaints that it ruins the game, it surely only levels the playing field - leaving takers and ‘keepers to once again battle it out in the game of wits and talent.
