Man Utd defender Jones: Beating Newcastle will put pressure on Man City
United can close to two points 24 hours before their rivals head to Merseyside.
Jones knows it is an opportunity that should not be squandered.
"City have done fantastically this season," he said.
"I am not taking anything away from them.
"But they do have some tough games coming up.
"I don't care how good you are, teams can be put under pressure. This is a difficult league to be in.
"It would be nice to reach top spot by Christmas. But it is not essential.
"Don't be writing us off if we are not there by January."
