Louis van Gaal's first few months in charge of Manchester United have been eventful, to say the least. The Dutchman arrived after guiding the Netherlands to the semi-finals of the World Cup, and immediately tried to bring his 3-4-1-2 system from the tournament in Brazil to Old Trafford.
In order to do that, van Gaal has spent over £150m on acquiring new talent, with Luke Shaw, Ander Herrera, Marcos Rojo, Angel Di Maria, Daley Blind and Radamel Falcao all arriving at the club. Whilst some have still yet to play for the club, the spending spree hasn't really helped as United are still without a win in the Premier League after two draws and one loss, whilst the 4-0 defeat to League One side MK Dons was one of the most embarrassing nights in the club's recent history.
The new signings should help United turn the corner, but the arrivals could actually cause United problems when it comes to keeping hold of some other players.
Spanish playmaker Juan Mata has already been linked with a January exit from Old Trafford with Juventus believed to be monitoring his situation, whilst reports this afternoon speculate that van Gaal has had to try and ease the concerns of wonderkid winger Adnan Januzaj.
The 19-year-old Belgian international broke into the United side last season and became an important player for the Red Devils, playing 35 games and scoring four goals in the process. Tipped for big things, Januzaj was expected to kick on again this season - but has yet to start a league match.
With new signings and a switch to 3-4-1-2 - which Januzaj doesn't fit in - the youngster has reportedly asked van Gaal to clarify his role at Old Trafford.
The last thing United want is another Paul Pogba situation, which saw United lose the French midfielder to Juventus after he was restricted from playing in the first team. Pogba has since become one of the top young midfielders in Europe with an estimated value of around £60m, and played for France at this summer's World Cup.
It's one of the biggest mistakes United have made recently, and with Paris Saint-Germain reportedly interested in Januzaj, van Gaal has to make sure that Januzaj is happy at Old Trafford - or risk losing one of the brightest young United players in recent years.
