Manchester City boss Pep Guardiola has kept the door open to Oleksandr Zinchenko leaving this week.
Real Betis want to take Zinchenko on a season-long loan with a €12m option.
Asked about the Ukraine international, Guardiola said: "With Zinchenko, we will see what happens at the end of the month, but right now he is with us in training.
"The situation is not easy for him, but I am impressed by the way he trains."
City accepted an offer from Wolves this summer, though Zinchenko turned down the move.
