Roberto Mancini’s men managed to salvage a 3-3 draw at the Etihad Stadium after falling 3-1 behind to Martin O’Neill’s men, but the result means United can open up a five-point lead at the top with victory at Blackburn Rovers on Monday night.
Dzeko, however, is convinced the defending champions will drop points in the run-in and still expects the Manchester derby on 30 April to play a key role in deciding the destination of this year’s title.
“There are seven games to play, and the way we dropped points, United can drop points as well, so everything is still open,” said Dzeko after the draw with Sunderland.
“We need to go from game to game and try to win every match. The next is Arsenal. We will play to win and then we will see.
“They are fighting for a Champions League place and are a top team, so it won’t be easy. It should be a good, open game.”
The 26-year-old added: “Maybe we thought Saturday was going to be easy. We had won all our home games so maybe we thought we could count on all three points – but it’s not like that, and you have to fight for every point.”
And Dzeko is hoping Steve Kean’s Rovers can spring a surprise at Ewood Park against Manchester United on Monday night. He said: “It is an important game for Blackburn as well so everything is possible.
“We lost points on Saturday, and they could drop them at Blackburn or somewhere else.”
