The four goals Manchester United have conceded against Porto and Fenerbahce on their European road trips this season have a common factor.
They all came from a flank patrolled by the same two players. Diogo Dalot and Marcus Rashford started on the left in Portugal, and Porto scored three times with attacks down their right.
On a couple of occasions, the full-back and winger were too casual in stopping crosses coming into the penalty area, an approach that cost them when it came to the first goal.
In Istanbul Dalot and Rashford were switched as a pair to the right, but the problems continued. Fenerbahce's equaliser came from an Allan Saint-Maximin cross and while the delivery was brilliant, Dalot and Rashford again failed to do enough to stop the ball coming in.
