Luke Shaw’s unlucky own goal was costly last night, and he handed United another problem too.
Minutes after Barcelona’s opener he was booked, meaning he will be suspended for the second leg.
Shaw, signed by United for £30 million, has been a regular at left-back and United do not have a natural deputy.
It leaves Ole Gunnar Solskjaer having to choose between a handful of makeshift solutions.
Unfortunately, one could be Ashley Young.
There might be one thing worse than Ashley Young at right-back…
Young played at left-back earlier in the season and last and is familiar with the position.
His woeful performance at right-back yesterday gives little confidence he will be an adequate fill in.
If Young moves to left-back the Diogo Dalot will have to slot in on the right.
The alternative options consist of Marcus Rojo, playing Dalot on the left, or Matteo Darmian if he is back from injury.
Dalot may be the best option, but that will mean Young will be in at right-back again.
As if going to the Nou Camp 1-0 down was not hard enough already…
