So in the Wolves match, McTominay exchanged passes with Ashley, then passed the ball to where Young had been stood, only for Ashley to have retreated while Scott was passing the ball, an unwise challenge followed, punished by a 2nd yellow card.
Then rewatching the Barcelona match, Fred has the ball after a corner, Young signals he wants the ball played ahead of him. Fred can't have noticed, as his pass assumed Young would be running in the opposite direction. Ball goes out for a throw-in.
In the same game, Lindelof moves forward past a Barca player, then passes sideways to Young, who is stood still, ball goes out for a throw-in.
There is no understanding between Young and his team-mates. Probably wasn't Ashley's fault in each case, possibly in none of them, but needs better communication because it would appear his team-mates have no idea if he is going to be running forwards, retreating backwards, or stood still.
On 2nd viewing, Young's performance against Barca was as horrific as it seemed first time around. Those crosses were just terrible.
