The transfer window re-opens in a matter of weeks, and Manchester United manager David Moyes is keen to strengthen his squad in order to seriously challenge for silverware in the final months of the campaign.
The Red Devils have been linked to dozens of players in recent weeks, but it would be a surprise if any of the big names end up at Old Trafford by February 1 2014.
Nevertheless, United fans can dare to dream, so let's take a closer look at the club's five dream January signings.
5. Sami Khedira | Real Madrid
Despite signing Belgium international Marouane Fellaini in the summer, Manchester United are reportedly keen to sign another tough-tackling midfield enforcer - and have identified Real Madrid's Sami Khedira as the perfect target.
The Germany international, 26, has played over 140 matches for Real Madrid since joining the Spanish giants from Stuttgart in 2010. However, he is likely to cost a whopping £35m to sign.
4. Ilkay Gundogan | Borussia Dortmund
Former Manchester United coach Rene Meulensteen recently answered the question of which central midfielder the Red Devils need most with the words "Ilkay Gundogan".
The 24-year-old has starred for Borussia Dortmund since joining the club in 2011, and is widely regarded as one of Europe's most talented midfielders.
However, in order to secure his services, United will need to fend off competition from both Arsenal and Real Madrid.
3. Marco Reus | Borussia Dortmund
Recent reports claim Manchester United are prepared to offload Shinji Kagawa back to Borussia Dortmund in order to sign Marco Reus.
The lively left-sided winger, who scored 19 goals last season for the Champions League finalists, would be a superb signing for the reigning Premier League champions.
Can United tempt Dortmund into selling the gifted Germany international? It seems unlikely, but plenty of stranger things have happened in the past.
2. Radamel Falcao | AS Monaco
Radamel Falcao has only been at AS Monaco for two minutes, but rumours insist he could leave the Ligue 1 club in January.
United are reportedly one of the clubs interested in the prolific Colombia international, who is arguably the world's best No. 9, but the Red Devils would need to smash their current transfer record in order to sign him.
Chelsea manager Jose Mourinho is expected to watch Falcao in action against Belgium later this week, while Real Madrid are also weighing up a move for the ex-Atletico Madrid hitman.
1. Robert Lewandowski | Borussia Dortmund
Robert Lewandowski was - and still is - expected to join European champions Bayern Munich at the end of the season.
However, there's a feeling that a Premier League club could snatch him from Bayern's grasp by tabling a significant offer for the in-form Poland international in January.
Lewandowski is only 25 and would be a stunning coup for United.
Fitting him into the current system would be tricky, of course, but that's a selection headache David Moyes would love to have.
