With Louis van Gaal under serious threat of losing his job in the near future, one man has stood out as the most likely candidate to take the reigns of the Premier league giants if he were to leave - Jose Mourinho.
Mourinho was sacked by Chelsea on the 17th of December, and within days was being linked to the Manchester United job.
Van Gaal seems to be negotiating his way through this tough period, but it is worth taking a look at a possible replacement in the event of his departure.

The man on most Manchester United fans' lips is that of the two-time Champions League winner.
It isn't surprising he is among the favourites for the job considering his reputation and record with his previous teams.

The Portuguese has won the league title at every club he has managed since his days at FC Porto over ten years ago. He has also won the Champions League on two separate occasions - a feat matched by Sir Alex Ferguson.
The former Chelsea manager certainly has the pedigree that Manchester United need, but his attitude off the pitch will concern the board members.
Mourinho has been in charge of five teams in the past 13 years; FC Porto, Chelsea, Inter Milan, Real Madrid and then back to London.
Another potential worry for the fans and the board regards the short period of time he spends at each club. His maximum term at any employer has been three seasons and this is something that Manchester United would want to avoid.
After the long spell Ferguson enjoyed with the club, United sacked David Moyes after less than a year in charge and with Van Gaal on the brink of being sacked after 18 months, the Red Devils will move further away from that philosophy if they were to employ a coach with such a short track record with teams.
Mourinho sets his teams up to be difficult to beat, a style key figures at Old Trafford will be reluctant to encourage after this season's criticism of Van Gaal's philosophy.
Jose Mourinho may be favourite to be the next United manager, and he may have the backing of some United fans, but with his track record, he might not be the logical solution.
All this, however, will be just words until the time comes for Van Gaal to leave to leave the club.
