When Manchester City and Manchester United meet at the Etihad Stadium on Monday, all the pressure to win and take command of the Premier League title race will be on the blue half of Manchester.
United are 19-time champions and have a squad full of players who have won every domestic title possible.
City are looking to end their title drought and win a trophy after another year of big-time spending on players in the transfer windows.
All the pressure is on City to win this match because if they fail, there could be major changes to the club in the summer.
Manager Roberto Mancini could be sacked, and several players such as Mario Balotelli may also find themselves out of the club by summer's end.
City have not scored a single goal in the last three league matches with United on their home pitch, and with Wayne Rooney scoring 16 goals over his last 14 matches, containing the Red Devils attack won't be an easy task.
After winning the FA Cup last season and making some strong summer signings, this was supposed to be the year that City finally got their hands on the league title and made a deep run in the Champions League.
Since their European campaign ended far sooner than expected, winning the league title is a must for the club.
After having a big lead in the table erased earlier in the year, City must show the championship poise and character necessary to become champions.
The pressure is on City and their players to prove they have what it takes to win massive games late in the season against top opponents with the title at stake. We know United can do that, and we have seen them do it many times in the Premier League era.
A loss for the Red Devils would be disappointing, but defeat for City against their hated rivals would be catastrophic.
