Manchester City have received a major boost ahead of Sunday’s Premier League meeting with Manchester United, with Nico O’Reilly confirmed as fully available for the highly anticipated Manchester derby.

O’Reilly has missed Manchester City’s last two games, but the latest update has provided plenty of encouragement ahead of the trip to Old Trafford. According to Enzo Maresca, the midfielder is now “100% available” and could be in contention to start against United.

With such a high-profile fixture approaching, the big question is whether O’Reilly should immediately return to the starting XI or whether Manchester City should manage his minutes carefully after his recent absence.

Nico O’Reilly Back in Contention

O’Reilly’s return could not come at a better time for Manchester City. The derby represents one of the biggest fixtures of the Premier League season, and having key players available can make a significant difference in a match where small details often decide the outcome.

The 21-year-old offers versatility and energy in midfield, giving City another option when it comes to controlling possession and dealing with Manchester United’s physical approach.

After missing the last two matches, there may naturally be some concern about whether O’Reilly is ready to handle the intensity of a Manchester derby. However, the fact that he has been declared “100% available” suggests there are no current fitness concerns that should prevent him from being considered for selection.

That should give City supporters plenty of confidence heading into Sunday’s encounter.

Should O’Reilly Start?

For me, the answer is yes.

If O’Reilly is genuinely fully fit, there is a strong argument for putting him straight into the starting XI. Manchester derbies are not matches where a manager can afford to hold back his strongest options simply because a player has recently missed a couple of games.

O’Reilly’s physicality, versatility and ability to contribute on both sides of the ball could be particularly important against Manchester United.

City will want to dominate possession, but they will also need players capable of winning second balls, covering ground quickly and responding when United attempt to transition from defence into attack.

O’Reilly can provide that balance.

His presence could also allow City to have greater flexibility during the match. If the game becomes more open in the second half, his energy could become even more valuable, while his ability to operate in different midfield roles gives the manager tactical options.

Why the Manchester Derby Could Suit Him

The nature of a derby makes O’Reilly’s qualities particularly attractive.

Manchester United are unlikely to simply sit back for 90 minutes. There will be periods where City have to defend transitions, compete for loose balls and deal with the intensity that comes with playing at Old Trafford.

O’Reilly has the energy to contribute in those situations.

At the same time, City will be expected to control the game through possession. That means their midfielders will need to be comfortable receiving the ball under pressure and moving it quickly.

Having O’Reilly available gives City another player capable of helping them maintain that control.

It is also worth remembering that returning from a short absence does not necessarily mean a player needs to be protected. If the medical and coaching staff are satisfied with his condition, starting him may actually be preferable to asking him to enter the match midway through when the tempo is already high.

City Have a Big Decision to Make

The decision ultimately comes down to how the coaching staff assess O’Reilly’s match sharpness.

Being medically fit and being completely match-ready are not always the same thing. A player can be declared fully available while still needing time to regain his rhythm.

That is why the starting XI will be closely watched when it is announced.

If O’Reilly does start, City supporters will expect him to bring energy and discipline to the midfield. If he begins on the bench, his introduction could provide City with an important second-half weapon.

Either way, his return is positive news for Manchester City.

My Verdict: Start Nico O’Reilly

If I were picking the Manchester City team for Sunday, I would start Nico O’Reilly.

The Manchester derby is a game where experience, intensity and tactical flexibility matter enormously. If the player is genuinely 100% fit, there is little reason to leave such an important option on the bench purely because he missed the previous two matches.

O’Reilly’s athleticism and versatility could prove useful throughout the game, particularly if Manchester United attempt to make the match physical and disrupt City’s possession.

The key, however, will be managing his workload if necessary. Should City establish control of the match, there would be nothing wrong with taking him off later in the game to protect him.

But from the opening whistle, I would want him involved.

The Manchester derby is scheduled for Sunday, September 13, with Manchester United hosting Manchester City at Old Trafford. The fixture promises to be another major test for both sides, and O’Reilly’s return gives City another selection option at exactly the right time.

So, would you start Nico O’Reilly against Manchester United?

For me, it is a clear yes. If he is truly 100% fit, get him into the starting XI and let his energy, versatility and physicality help City attack one of the biggest fixtures of the Premier League campaign.
