Manchester City and Manchester United played to a 0-0 derby stalemate on Thursday, with Marouane Fellaini's sensational sending-off the highlight at the Etihad.
Pep Guardiola and Jose Mourinho are accustomed to competing for league titles, but their sides are simply scrapping for a place in next season's Champions League, and the result did little to change their battle for fourth place in the Premier League.
Manchester City maintains a one point lead over its red rival (65-64) with five games to go in the campaign. Both have a game in hand on Liverpool (third place, 66 points).
Both teams were shorthanded, with Zlatan Ibrahimovic and Marcos Rojo done for the season for Manchester United, while Paul Pogba and Juan Mata were ruled out by Mourinho.
Manchester City, meanwhile, was without David Silva and John Stones, though Sergio Aguero was fit to play and started, while Gabriel Jesus made his return from a broken foot suffered in February as a late substitute.
It was Aguero who nearly struck first for Manchester City, with Kevin De Bruyne whipping in a cross that the Argentine side-footed off the near post in the ninth minute.
Claudio Bravo nearly gifted Manchester United the lead in the 24th minute, making an acrobatic and impressive dive to swat a cross away, only to hit it right into the path of Henrikh Mkhitaryan inside the box. Bravo regained his positioning and made the subsequent save, though, keeping it 0-0.
Bravo's counterpart came up with a sensational save on other end in the 31st minute. Aguero let rip from 25 yards, but David De Gea made a fantastic diving save, catching the ball to prevent any rebound. De Gea made another save on a chance from Aleksandar Kolarov, who tipped his chance around the post four minutes later.
Ander Herrera had an opportunity just before halftime to give United the lead, with Marcus Rashford whipping in a free kick toward the far post. Herrera had a clear look at a header, but he put it wide of the post instead of trying to hit it back across goal.
With United content to defend, City continued pressuring, with Aguero doing most of the damage in the final third, but to little avail. City earned a 67th-minute corner kick that led to a Nicolas Otamendi header from seven yards out and straightaway, but it was deflected out and over the bar.
City was forced into a goalkeeper change in the later stages, as Bravo exited in the 79th minute with an apparent left calf injury. It occurred when he leapt off his line to claim a corner kick. He was replaced by Willy Caballero.
Manchester City was gifted a man advantage in the 84th minute when Fellaini was sent off. Not even a minute earlier he had been booked for fouling Aguero, and then after another incident–which could have resulted in second yellow–he headbutted Aguero right in front of referee Martin Atkinson, who promptly gave him marching orders.
City couldn't take advantage of the extra man, though, with Gabriel Jesus's converted header in stoppage time being rightly disallowed for offside. The sides split the point and continue their battle for fourth as the season hits the home stretch.
