Having won all but one of their games this season, it's fair to say Manchester City are looking unstoppable, and Gabriel Jesus and Sergio Aguero have played huge parts in that.
The South Americans have contributed 20 goals for the Citizens, scoring ten each, as well as adding five assists between them.
City are eight points clear of neighbours Manchester United at the top of the Premier League table, and have secured qualification to the knockout stages of the Champions League, scoring 12 goals in four matches, beating Serie A leaders Napoli twice.
With such a plethora of talent at his disposal, Pep Guardiola has been able to rely on anyone he selects, with Leroy Sane, Kevin De Bruyne, David Silva, Raheem Sterling and Fernandino all chipping in with goals and assists.
Defensively, City have improved no end from their issues last term, which proved their downfall in the title race, with Ederson looking a solid acquisition between the sticks, while the form of John Stones has really stood out.
You would, therefore, be forgiven for thinking Guardiola doesn't have any real dilemmas in his second season at the club.
However, the Spaniard has had to rotate between Aguero and Jesus up front, with their 4-2-3-1 formation only finding room for one of them.
The former Barcelona and Bayern boss called it his 'toughest decision' to select one of the pair, but he answered the question we have all been wondering; why can't they play together?
According to Pep, it is down to the injury of Benjamin Mendy.
Mendy is out until April following his ACL injury, and Delph has been converted into a makeshift full-back to fill the role.
"Both have different qualities - they deserve to play. They have a lot of games and they have to be ready. It is the toughest decision," he said.
"Yeah in the moment we had Mendy [they could play together]. When you have Mendy, he can play wide and the winger can go inside.
"Fabian Delph cannot do that. Without Mendy, Leroy Sane has to go wide, which is why they don't play together.
"Sergio after the crash, he was fit. He is fit. For me he is so tough. So is Gabriel."
With City already looking like certainties for the Premier League, it is scary to think how much more deadly they would be had Guardiola been able to use the South Americans together.
Unfortunately for Aguero and Jesus, it looks as though they'll have to get used to the constant rotation until April at least.
