Anyone who uses to term 'back up' needs to understand the era of football we are playing in and the manger we have at the moment. Football is no longer a game of 11 players and one sub. We will use different players depending on the opposition and the way we want to play. We will never fit Kevin silva silva sane Aguero Jesus Sterling and gundogan in the same team but it doesn't mean any of the above are back up/reserve players. We are looking to compete for four trophies next season and that means both Danilo and walker will play plenty of games. Plus the fact that a competitive squad with who players competing for every position brings the best out of every player.
