Pep Guardiola says Kyle Walker is in the team to combat Vinicius Junior's pace as well as help the team.
Guardiola changed seven players for the Premier League win over Leeds at the weekend, citing tiredness among some key players. With Nathan Ake injured, one change vs Real Madrid was enforced as Manu Akanji plays at left-back and Walker comes back in. However, five other changes saw Bernardo Silva, Jack Grealish, Rodri, John Stones and Ruben Dias return as City looked to establish a first-leg lead to take back to the Etihad in this Champions League semi-final.
Walker will have a tough job on his hands coming up against the rapid and skilful Vinicius, who is one of the in-form players in the world and was sublime in the Copa del Rey final triumph against Osasuna on the weekend. Walker is one of the few players capable of matching the Brazilian's speed and is set for a busy night.
