Manchester City manager Pep Guardiola says Newcastle are one of six sides who pose a threat to his team's bid for a third straight Premier League title.
City are well placed to become only the fifth English club - after Arsenal, Huddersfield, Liverpool and Manchester United - to achieve the feat.
Victory against Fulham this weekend would put City back to the top, ahead of Arsenal, at least for 24 hours.
However, Guardiola said he is taking nothing for granted.
The former Barcelona and Bayern Munich manager says he can still see title challengers everywhere - including Liverpool, who are 13 points behind City, and Newcastle.
