Manchester City midfielder Ilkay Gundogan said Saturday’s derby will be their biggest test in recent years.
Pep Guardiola’s men travel to Old Trafford days after they were eliminated from the Carabao Cup by Southampton.
Since their 2-1 win over Liverpool in August, no team has won more points than United in the Premier League.
The Red Devils have collected 35 points and are sitting in fourth place in the table.
“United are in a very good moment now, full of confidence, they are hungry, they want to win.
“They seem to be starting to click between them so it will be a very difficult game – probably the toughest Manchester derby for us in recent years.
“Going to Old Trafford is always special, it’s going to be really tough, and we need to do a lot better,” Gundogan said.
City are second on the log, five points behind leaders Arsenal.
