The Blues are currently working under an EFL-imposed business plan and as such are seemingly restricted in some aspects including player retention.
The Blues captain has been a loyal servant since joining the St Andrew's club permanently in January 2015, and has made 159 appearances to date between his permanent spell and his prior loan spell (Transfermarkt).
However, his contract expires at the end of the season and, due to a business plan imposed by the EFL in August, the Championship club is currently awaiting confirmation on whether it can be extended.
According to the Birmingham Mail, some of the areas affected by the business plan are the Under-23s, existing contracts, new contracts and prospective new signings.
With Morrison having just seven months left before his contract expires and little progress in the field, Monk was left to bemoan the whole situation at his pre-match press conference.
“The players are fully aware [of the business plan issues], and I’ve spoken to players like Michael, not being able to do those sorts of things is not ideal to secure those players’ futures," the 39-year-old is quoted by the Birmingham Mail as saying.
Asked if he was worried about Morrison leaving, Monk replied: “No. That’s out of my control. The players know how I see them, and they repay that in terms of their performances and their spirit in terms of how they do it. That’s all we can do because of the restrictions we have."
Morrison arrived at Birmingham on an initial loan spell from Charlton Athletic in October 2014 but as soon as the transfer window reopened, he left the Addicks on a permanent basis.
Since then, the 30-year-old has gone on to be a crucial player for several managers and the successor to Paul Robinson as club captain.
