Ederson ended up staying, but Man City are still monitoring potential options to replace him, with Costa highly regarded by Guardiola as an ideal possible replacement.
However, Porto have set Costa’s asking price as high as €75m, which is higher than what City would be willing to pay. CaughtOffside understands that City value Costa at closer to €45-50m, and this discrepancy suggests that any transfer negotiations could be challenging.
Costa himself is understood to have expressed an interest in moving to the Premier League if the opportunity presents itself, with the Portugal international perhaps understandably keen to challenge himself at a higher level before too long.
