Manchester United's loss to Newcastle on Sunday meant they slipped further away from Premier League leaders, and rivals, Manchester City. 

Pep Guardiola's side are now 16 points clear at the top of the table, while Jose Mourinho's team are now just four points ahead of fourth-placed Tottenham. 

With the challenge for a Champions League spot tighter than ever this season, United's back-to-back away defeats are not good reading for Mourinho. 

Despite securing even more attacking firepower in the January transfer window, the Red Devil's couldn't break Newcastle down at St James' Park and lost 1-0. 

Matt Ritchie scored the winner and after the game, Mourinho appeared to blame Paul Pogba for costing United the game, with his involvement in the build-up to the goal.

The £89 million midfielder didn't challenge for a header on the edge of the box after the ball was swung in from the Newcastle free-kick that Ritchie scored from.

Moments later, Pogba was subbed off, failing to complete 90 minutes for the third game in a row, suggesting his form has really dipped in recent weeks.

After being dropped for United's win against Huddersfield Town, reports suggested that the Frenchman had a row with his boss, and he's now apparently made another demand to Mourinho.

According to L'Equipe, Pogba has become frustrated about playing in a midfield partnership and has demanded that Mourinho uses him on the left side of a midfield three. 

The 24-year-old is often played in a deeper role alongside Nemanja Matic, but recent defeats have exposed United's failure to protect their defence. 

If Mourinho is to listen to Pogba's demands, he will have to alter his formation, coming away from the 4-2-3-1 system he's used for much of his time in Manchester. 

Changing shape would allow Pogba more freedom to express himself in an attacking sense, giving him less defensive responsibility. 

After paying so much to bring back the hottest midfield prospect in the world two years ago, Mourinho should at least give him the chance to play where he wants. 

And if it happens, Pogba could reach an even higher level, as well as pull himself out of a poor run of form.
