The Premier League champions have been linked with the Ligue 1 pair for some time, with rumours suggesting that winter offers for one, if not both, are already being prepared.
But, United will have to fend off Serie A giants Roma if they are to land the players.
The Italians are keen on both, with new boss Rudi Garcia having a deep knowledge of the French top tier.
Ghoulam has been heavily linked with United in recent weeks, with David Moyes thought to see the Algerian as a potential replacement for Patrice Evra.
The Saint Etienne man has been in excellent form, and is seen as a cost-effective alternative to Leighton Baines.
Cabella is also on Moyes’ radar, with adding more creativity to his midfield a priority following a disappointing start to the season.
The 23-year-old is widely thought of as one of Ligue 1’s best playmakers, and is thought to be available for around £15m.
