Manchester United went 1-0 down tonight against CSKA Moscow thanks to a controversial Alan Dzagoev goal. Manchester United players and fans were furious that the goal was allowed given the apparent off-side position of the goalscorer.
Manchester United supporters were not happy about the decision.

Once again the extra official behind the goal working well in games! What is the actual point in them. Moscow boy offside right in front of him #WasteOfTime

However, it appears under UEFA's rules the decision was actually the correct one.
The rule does state that a player behind the goal line is still technically in play, thus Blind played him on onside.
Regardless, Manchester United were able to overcome the goal anyway, grabbing two quick second-half goals to turn the tie on its head.
