Who do Manchester United need to sign in the January Transfer Window?

Ole Gunnar Solskjær's sensational start to life at Manchester United has awoken the giant of the English game. Solskjær's six wins in his first six games is a new club record, but what has been most impressive about these victories is the manner in which these games were won.A refreshing brand of attacking football has been praised by fans and media alike for being more in line with the ethos of the 20-time English Champions. The team relieved from the defensive instructional constraints of Jose Mourinho seems more free and willing to positively and confidently approach games. Every player from World Cup winner Paul Pogba to English hotshot Marcus Rashford have found great form since the departure of Jose Mourinho.But while this start is commendable can we assume that the Red Devils have somehow become world beaters overnight? Putting things into perspective, four of Manchester United's five league victories, while impressive, came against Cardiff City, Huddersfield Town, Bournemouth and Newcastle United.All four of these teams have lost to every single team in the top 6 in the Premier League this season. In fact, every single point Manchester United has lost this season has been to a team who has taken points from another top 6 team.So even the now struggling Arsenal has dispatched all of these teams including putting four goals past the final challenger Tottenham. In that Tottenham game, despite the United victory Spurs dominated for long periods only to be denied by the heroics of David De Gea.De Gea's 11 saves in the second half alone is a season-high. Tottenham head coach Mauricio Pochettino even said after the match he was happy with his team's performances at Wembley in spite of the defeat and compared his mood to his dissatisfaction at the performance at Old Trafford in the first encounter this season.Amazingly at Old Trafford Jose Mourinho's United out-shot and out-possessed Tottenham. In Wembley, United had fewer shots and possession under Solskjær. This 1-0 victory, as well as the ease of previous fixtures, may have masked some of the apparent deficiencies the club still has.The mood in the camp is good, the momentum is excellent but are all the issues solved? Is this team now strong enough to compete for trophies? To even chase for the top four? Let's look at some players Manchester United can bring in this Winter window to help with those objectives.Kalidou KoulibalyFC Internazionale v SSC Napoli - Serie AThe Senegalese international is number one on this list. He has been linked with Manchester United for several seasons now for obvious reasons. This mountain of a man has been Napoli's rock since 2014 and has made the Serie A team of the Year for the last three seasons. Considering the quality of central defenders in Italy that is quite some achievement.Jose Mourinho practically begged for a central defender in the summer and was linked to almost every available option during that window. In the end, the window was shut and the void remained opened. A void, quickly exposed this season with United's defence practically leaking goals. Has these run of games lessened the need of such a player or does Manchester United still need improvement at this position?Whatever Ole decides Koulibaly is still a player that at 27 years old has the potential to have a Virgil van Dijk effect on any team. The player won't come cheap and would probably be the most expensive defender of all time if a deal is done. Support from Paul Pogba over a race-related incident in Italy increased rumours that Koulibaly might be on his way to Manchester.Also see : Fantasy Premier League , Fantasy Premier League Tips, EPL Transfer News
