Manchester United could really do with a consistent penalty-taker right now.
Paul Pogba has missed twice from the spot this season, though he converted one of those on the rebound.
Alexis Sanchez, meanwhile, has fluffed his lines in three of his last seven attempts for club and country.
That said, Anthony Martial made no mistake when he stepped up in the 3-1 defeat to Manchester City before the international break.
Romelu Lukaku was fouled by Ederson just seconds after coming on and his French team-mate did his best to get United back into the game.
There were few positives to take from the Derby Day disappointment, except that Martial's goal marked the Red Devils' 100th successful penalty in the Premier League era.
Granted, a few of them have been contentious over the years, but the club have noted the occasion by comparing some of their greatest modern penalty-takers on their official website, courtesy of some help from Opta.
Eric Cantona was unveiled as the most effective, scoring 87.5% - that's 14 out of 16, missing against Blackburn and Leeds.
Louis Saha never missed - at least in the league - scoring all four he was awarded.
Yet, in the 21st century, two obvious names spring to mind - Cristiano Ronaldo and Wayne Rooney.
The Portuguese obviously took fewer penalties because he spent just six years at Old Trafford compared to Rooney's 13.
The stats certainly make interesting reading. In terms of goals scored, the former England captain is United's most prolific penalty-taker, netting 20 - more than any other player.
The 33-year-old also missed eight, though, bringing his ratio down to 71.4%.
There's little doubt about the most important of those. Rooney sealed the title on May 14 2011 by blasting the ball past Paul Robinson against Blackburn at Ewood Park.
Ronaldo's success rate
Ronaldo, meanwhile, scored 11 of his 13 attempts in the league, placing him second after Cantona with 84.6%.
Wigan and West Ham were the only sides to thwart the five-time Ballon d'Or winner from 12 yards.
So, while he missed in that memorable Champions League final shootout against Chelsea in 2008, he was highly effective in domestic football.
The verdict? Rooney scored more, but Ronaldo had a higher success rate.
It comes as little surprise, given his reputation - and the somewhat derogatory nickname 'Penaldo' - that he continued that form at Real Madrid.
Of the 71 he took for Los Blancos in La Liga, he scored 61.
You could usually rely on both Ronaldo and Rooney in their prime - Jose Mourinho would dearly love to have another forward like that on the books now.
