After an electric start to the season, Manchester United have crashed back down to earth in recent months.It looked like fans were going to get a two-horse race for the Premier League title contested between both Manchester clubs, but the Red Devils have fallen a massive 14 points behind their local rivals at the top of the table.After a run of three draws - against Leicester, Southampton and Burnley - boss Jose Mourinho's frustration was palpable and something needed to change.After earning a victory over Everton at Goodison Park and following that up with a win in the FA Cup over Derby, United now have back-to-back wins and with the January transfer window opening, things are starting to look a bit more promising.Will the United board back Mourinho with the club so far behind their rivals?According to Sky Sports, the club are interested in making a deal for Paris Saint-Germain winger Lucas Moura.The 25-year-old Brazilian would cost around £20 million and there are plenty of reasons why the deal would work.For one, PSG have to be mindful of balancing their books with Kylian Mbappe set to join permanently at the end of the season for around £160 million and they have FIFA Financial Fair Play rules to comply with.

Secondly, with the wealth of attacking talent in the French capital, Moura has only made six appearances off the bench this season and would be eligible for United in the Champions League.

Factor in United's need for a right-sided winger and the deal seems like a no-brainer, but a lot of United fans on Twitter have one reason why they don't want Moura.

United were primed to sign a then-teenage Moura back in 2012 from Sao Paolo, but PSG ended up outbidding United and paying £35 million for his services.

The Old Trafford faithful have not forgotten the choice the winger made, even if it was Sao Paolo's choice really.

Mourinho's men face Stoke in their next fixture and will look to take advantage of former striker Mark Hughes' recent dismissal from the club.
