After a one year absence the Red Devils are back in the Champions League and have been rewarded with a fairly difficult group.
Despite being number one seeds, Memphis Depay's former club PSV are arguably the weakest team in the group and potential whipping boys. Alongside last season's top goalscorer, Depay, who was sold for £30 million, Georginio Wijnaldum, who scored 18 goals in all competitions was sold to Newcastle United for £14.5 million.
PSV may have won the Eredivisie at a canter last season but were thoroughly battered by Zenit St Petersburg (4-0 on aggregate) in the last 32 of the Europa League. They also only won two out of their eight games in Europe last campaign. Now that they are without their two best players Phillip Cocu's men cannot be expected to contenders for the two automatic qualifying spots.
However, CSKA Moscow have time and time again shown they are a credible side. The Russian Premier League side are notoriously difficult to play in their home ground Arena Khimki.
United's fierce local rivals, Manchester City, know all about CSKA having been drawn against them in the last two Champions League Group Stage phases. Although the Russian side finished last in the previous Champions League campaign, they drew with Roma and Manchester City at home (1-1 and 2-2) before rocking City at the Etihad and winning 2-1. They also had every chance of qualifying in the very last game but were humbled by Bayern Munich in a 3-0 loss at the Allianz Arena.
The side are managed by Dieter Hecking and have made massive strides under the German boss. He steered them to their first ever cup wins in the DFB-Pokal and DFL-Supercup in 2015 by beating Borussia Dortmund and Bayern. Wolfsburg also finished as runner-ups in the Bundesliga for the first time behind Bayern.
However, the star-men of the side are Ricardo Rodriguez and De Bruyne. Rodriguez is an attacking full-back who is quickly developing a reputation as one of the best in Europe in his position, but he is aided by the fantastic partnership he enjoys with Belgian playmaker De Bruyne.
If the former Chelsea man does indeed leave, it is unknown whether Wolfsburg will have enough time to replace him or indeed how his departure would affect the club. The 24-year-old won the Bundesliga Player of the Year and Footballer of the Year Award in Germany after scoring 16 goals and assisting 28 in all competitions last season.
