Manchester City winger Jesus Navas believes today's result against Manchester United will be decisive in the title race.
Navas expects to start at the Etihad.
"The results of games such as this have a big influence on the title," he said.
"The winners will come away full of confidence, reinforced, it can be a springboard to better things. A derby such as this is like a six-pointer, when the two teams are so close to each other."
