Manchester City boss Pep Guardiola says Ruben Dias will travel with the squad to Madrid ahead of the quarter-final second leg against Atleti on Wednesday evening.
The Portuguese skipper has missed the past six weeks with injury but returned to training on Monday.
“He travels with us, the rest are fit," said Guardiola, who was then asked if there was potential for Dias to be in the starting XI.
“From the beginning tomorrow? No," he said.
“He did one training session after six weeks off.
“It is premature, but the fact he is back with the schedule we have is good. Everyone will be important and Ruben is."
