Look at it another way. Say you're Kun, and PSG and Madrid ring up and say "you'll be our undisputed number 1." You then talk to Pep and Txiki who tell you "you're one of five strikers that we're counting on. we want you to stay here but we aren't going to guarantee you anything other than you'll play some games and not play others".
What would you do?
As much as we want Kun to stay and be part of the squad, the truth is that he walks into the best XI at PSG or at Madrid. If either of those clubs come calling, my best guess is he'll want to go. If he does then City will let him for the right price.
Equally if Kun says he wants to stay then he be sold no matter what the offer. The ball's in his court, but the fact he sought out a journalist to deliver his "i've got three months to help the team then we'll see what the club wants to do with me" suggests to me that there's much more to the story than just the usual paper talk. After all, his answer Sunday was a BIG change in tone and attitude from when he was last asked about his future and he said words to the effect of "i'm not going anywhere i'm really happy here and after I finish my contract here I'm going back to Argentina".
It's an easy story to write, the new kid in town is scoring for fun and Sergio is quite rightly, having to bide his time on the bench.
Personally, I think Sergio will be leaving us this summer, despite City's best efforts to say otherwise, derail the season at a critical juncture.
Sergio has a complicated personal life and we have been very fortunate to have his best years at our club, a legend, who should be carried shoulder-high off the field and a statue immortalising "his" moment if he decides to move on.
Football changes very quickly and next week he could be scoring a hat-trick or winning us a Champions League trophy.
Whatever he decides, we should back his wishes and I'm sure his exit path would be done with good faith on both sides.
He's a couple grades down on what his immense standards were, regardless of his incredible scoring record. Sergio had it in him to score 40 goals a season in this league.
We should not look a gift horse in the mouth if Paris or Real do come calling. To achieve £70m plus for a player turning 29, next-year, in comparison to what we paid and what he has achieved since, is the perfect time and it won't come again.
A chance to bring in someone much younger but with the talent to try and match Sergio's incredible feats.
It would be Dybala or Griezmann for me.
The latter, would be great for shits and giggles, should Atletico consider it an attractive deal giving them £40m plus Aguero to go back there.
Make no mistake, United and Chelsea are planning their next move - they only have money - we also have unbelievable leverage with someone such as Kun.
