Manchester City have suffered a double injury blow ahead of facing Real Madrid.
Real will host the first-leg of their Champions League quarterfinal tomorrow night.
City trained this morning at the Etihad Campus in England before traveling to Madrid for the first leg of the quarterfinals.
At no point in the training session were Walker and Ake seen. Neither defender were on the pitch, both are injured and already were missing against Crystal Palace last Saturday.
The pair were missing from the squad named and due to board their flight to Madrid today.
