Eric Bailly is questioning his future at Manchester United, according to reports.
The Red Devils are locked up in talks for Leicester City centre-back Harry Maguire.
Leicester have frustrated United with their stubbornness as they want at least 80m for the 26-year-old.
Should the deal get done before August 8, Maguire would be the seventh senior centre-back in Ole Gunnar Solskjaer's squad.
Metro says the possibility of a logjam in the defensive ranks has made Bailly think about his future.
Bailly has one year to run on his current contract, but United have an option to extend it by a further 12 months.
