If no agreement is reached City face the prospect of the case being handed to a panel for a non-negotiable decision.
Neither the club nor UEFA would comment but it is understood the City have been negotiating forcefully for a significant reduction in that sanction but have been struggling to make progress.

Manchester City manager Manuel Pellegrini insists he is not worried by the possibility of the club being sanctioned by UEFA for breaching financial fair play (FFP) rules.
City are among a number of clubs, including Paris St Germain, that are having their cases considered this week by UEFA's Club Financial Control Body's (CFCB) which will decide if they have committed breaches of the break-even rules.
Asked if he was worried about the possibility of sanctions, he said:

No. First of all it is important to know what UEFA will have to say and then we can have an opinion.
It is important for the club but I am not the person in charge of those kinds of things.
Manchester City will find out this week whether they will face sanctions over possible breaches of new financial rules put in place by European football's governing body UEFA.
UEFA’s Club Financial Control Body (CFCB) will meet on Tuesday and Wednesday to discuss 76 cases, including Manchester City.
The Daily Telegraph is reporting that City will be found guilty by the CFCB. However, the club won't face a transfer ban, as the newspaper suggests. It is not one of the sanctions available to UEFA.
Any punishment would be decided in May.
