Manchester City legend Francis Lee had a method that was tried and tested when it came to taking penalties.
“I just hit the ball as hard as I could,” said the man who once scored a British-record 13 times from the spot for City in one top-flight season and added another two in the cups.
“If I didn't know exactly where the ball was going then what chance did the keeper have?”
It's a simple but sage piece of advice for those players who now wear the Sky Blue shirt – especially as it was Lee's spot-kick that proved to be the winner when City lifted their only European honour 51 years ago.
Don't over-think it.
Because if Pep Guardiola's side win a penalty in the Champions League final, there's a very good chance they will miss it.
Sergio Aguero's woeful attempt at trying to score with a Panenka when City were 1-0 up against Chelsea last Saturday and closing in on the three points they needed to win the Premier League title summed up their dreadful record from the spot during Guardiola's reign.
In the end, City's championship celebrations were delayed only a few days until rivals United lost to Leicester to confirm the Blues' third title in four seasons.
But in Guardiola's five years in Manchester, the Catalan has seen his side miss 20 of the 61 penalties awarded to them.
Aguero has failed with 13 of his 55 penalty attempts during a decade at the club – after only missing once from the spot earlier in his career.
But in recent years, if it isn't the Argentine missing from 12 yards then it's Kevin De Bruyne, Gabriel Jesus, Raheem Sterling, Ilkay Gundogan or Riyad Mahrez.
For a team graced with so much technical ability, it's an embarrassing statistic.
It reached a point in February that when the Blues were awarded a penalty against Tottenham, up stepped keeper Ederson to offer his services.
Rodri took the kick and scored. Just.
It's likely that Mahrez will be asked to do the honours if selected against Chelsea on May 29, after his nerveless finish from 12 yards against Paris St Germain in the semi-final.
But what makes City's record from the spot even more mystifying is that when it comes to penalty shoot-outs, they are nothing short of perfect under Guardiola.
City have beaten Leicester twice, Wolves, Liverpool and Chelsea during his time at the club – and lost none.
Going back even further, City have prevailed in seven of the eight shoot-outs since Sheikh Mansour's takeover in 2008.
Their only defeat came at Brighton, just 23 days after the Abu Dhabi United Group came in to transform the club - and Albion were in League One and playing home games at the Withdean Stadium.
City fans will recall with some relief that arguably the biggest game in the club's history was won in a penalty shoot-out.
It will be one day shy of the 22nd anniversary of their League Two play-off final victory over Gillingham when they step out in the club's first-ever Champions League final.
City prevailed that day after scoring twice in injury-time to force extra-time and penalties.
And former chairman David Bernstein later admitted that the move from Maine Road to the Commonwealth Games Stadium in East Manchester would have been impossible if City had remained in the third tier of English football.
It was the stadium – now renamed the Etihad – that proved to be one of the deal-making factors when Sheikh Mansour was looking at potential clubs to buy.
For all the quality that Guardiola has at his disposal, how he must yearn for a spot-kick specialist like Yaya Toure or Mario Balotelli.
Between them, they had a perfect record from 22 efforts from 12 yards, both men using disguise and accuracy rather than the sheer power preferred by Lee in 1970 against Gornik Zabrze in Vienna.
