Dzagoev put CSKA ahead at Old Trafford in controversial fashion!

United dominated the first half at Old Trafford but it was CSKA who went in at half-time one goal ahead after Dzagoev's goal. 

Vitinho stabbed goalwards from the edge of the area and the ball struck Dzagoev, who appeared to be in an offside position, on the back before nestling in goal!

Not everyone thought the goal was offside, but he does look like he is in an offside position...

Check out the goal for yourself below:
