Arsenal boss Arsene Wenger is convinced Manchester United can still slip up.
Wenger believes there could still be a twist in the title race even though Manchester United are seven points clear of City at the top.
"It is still very open. When you watch the games, no team today goes into a Premier League game and is sure to win it," said Wenger.
"Therefore I believe every team can drop points. It is much more open than people think it is. You see Man United as well, they win their games because they score many goals, but it is difficult for everybody."
