Ilkay Gundogan reckons Manchester City face their biggest derby test of recent years at Old Trafford on Saturday.
Pep Guardiola's champions go into the clash with United on the back of Wednesday's 2-0 EFL Cup defeat away to Southampton. Since their 2-1 win over Liverpool on August 22, no team has won more points in the Premier League than United, who have amassed 35 to rise to fourth in the table.
It is a remarkable turnaround, given United were rock bottom of the Premier League after two games, after humiliating defeats to Brighton and Brentford. Midfielder Gundogan has been impressed the way Erik ten Hag has transformed United in his first season and claimed City will need to raise their game if they want to win.
