Erik ten Hag is not making the most of the £19m Manchester United gift Ole Gunnar Solskjaer left him

Stop me, oh, stop me. Stop me if you think that you've heard this one before. There was a worrying sense of déjà vu about Manchester United's concerning Coventry collapse and the way in which the side wilted in the final stages of the match as they came under pressure.

Yet, just as predictable as United's regression, was the cast of players who let Erik ten Hag down once again this season, but who still found themselves in the starting line up.

Aaron Wan-Bissaka was poor, but there was a caveat in that he isn't a left-back. Casemiro struggled, but he too isn't a centre-back and was filling in for the greater good of the team. Then there was Marcus Rashford. No excuses can be made about his dismal display in his favoured position.

Rashford has always wanted to play on the left wing but is still living off the past glories of the world-class form he reached last season. It is true, that when at his best he is unplayable. But when he is at his worst, he shouldn't be played at all.

The 26-year-old started brightly at Wembley Stadium on Sunday afternoon but after a stray pass and a poor finish his head began to drop and his decision-making suffered. Rashford, so often a solo operator in a dysfunctional side, has a habit of going things alone. In the past his individual brilliance has been required, right now, they need him to be a piece in the bigger picture.

A by-product of Rashford's role on the left wing is that Alejandro Garnacho has been repurposed to the right, even though his playstyle is better suited to the opposite flank. It has often felt like Rashford's own needs have been put ahead those of the team. Another knock on effect of this is that it has also limited the opportunities for those in reserve. It was the case once again against Coventry.

In the wake of Coventry's equalising goal, Rashford was finally replaced by the industrious Amad Diallo. He did more in the subsequent half an hour than the England international had done in triple the amount of time on the pitch. Amad brought energy and excitement to the United attack at a vital stage of the game and if they would have found a winner, then it would most likely would have had something down to him.

In one of his first involvements in the match he expertly controlled the ball with his chest and span around his marker to launch a counter-attack that ended with Bruno Fernandes firing low at the 'keeper. A few moments later it was his hold-up play and awareness that set-up Fernandes again as he fired a ferocious effort off the underside of the bar. He continued to do so throughout his time on the pitch, holding onto the ball in tight positions and always looking to bring his teammates into the game rather than doing things on his own.

It is true that part of the Ivorian's success came from the fact he was introduced as a substitute who had little to lose after the wider failings of the team, but irrespective of the context of his performance, it was another showcase of the untapped potential he has to offer.

It would have been little surprise to the Coventry fans either. They experienced first-hand what he could do when he shone at Sunderland last season, including a superb goal he scored away against them as part of a successful loan spell that saw him crowned PFA Championship Fans' Player of the Year.

Three years after he officially completed his £19 million move to United from Atalanta under Ole Gunnar Solskjaer, we have yet to really see what he could do in the first-team environment, but now there is little excuse left for him to be overlooked again. With home matches against both Sheffield United and Burnley this week, games in which even this United side will be expected to win, there seems no better time for Amad to finally get the starting roles he has waited for.

It is clear something has to change and one of those should be in attack. We have heard this one before.
