Manchester City striker Gabriel Jesus has declared Sunday's clash with Manchester City as a 'must-win'.
Although it is early in the season, City are five points behind the reigning Premier League champions.
"It's a very important game for us, it's a direct confrontation against the leader of the table," Jesus said.
"We need to win those three points if we want to aspire to win the Premier League again. We need to be very focused, especially playing at home. We need to play our way and try to win the game."
