Since the New Year, Gundogan has been lethal in front of goal.
Saturday's double took him up to nine in as many Premier League games, all of which have been won by City as they have shot to the top of the table.
None of Lionel Messi, Cristiano Ronaldo or Robert Lewandowski can match Gundogan, who is the top scorer across all of Europe's 'big-five' leagues in 2021.
And were it not for a missed penalty last weekend against Liverpool, he could now already be on double figures before the middle of February.
Gundogan is also gunning for a national best in England's top flight.
