Just a year and a half ago, he already extended his contract with the club (until 2027), now it is obvious that he has turned into a top player and City wants to sign him with an obviously longer contract and a larger compensation amount. This probably won’t be difficult to do, since Foden has been a City fan since childhood and is as loyal as possible, but if I were him, I wouldn’t be in much of a hurry, since there are still 3 years ahead - why rush? Plus, he's already won everything he could with City, so maybe it's worth leaving some room for maneuver.
You have a good point there as well. Considering his current contract still has three more years to expire there isn't any need to be in a hurry to sign another shortly.
Besides he should think about the possibility of Guardiola's departure in the future as well. We all know Guardiola built this squad according to his system completely. In case of his decision to leave just like Klopp has done next manager choice will be really important for Manchester City. If they can't bring a manager who will continue with a similar system then things can get really interesting. However I assume they would think of bringing Arteta in that case who was already Guardiola's assistant before.
You mentioned playersanother bag of worms. Guardiola's method is like a custom suit - not everyone can wear it well. The new manager must respect Pep's work and modify it to keep City competitive, especially in Europe. We've seen clubs tank after a management change, and I don't want that for City. Players should tread carefully during this tricky moment, as you said
