Ruben Amorim can unleash Manchester United's next teenage debutant vs Everton

Few head coaches or managers turn to their substitutes' bench quite as often as Ruben Amorim does, which must have made it all the more difficult for the Manchester United boss to ignore his replacements at Tottenham last weekend.

Amorim usually uses all five substitutes in a game, and his record since he's been at Old Trafford shows how often he likes to turn to his bench. Until that game at Spurs, he made 90 out of a possible 100 changes in his 20 games in charge, only twice making just three in-game alterations.

The 40-year-old's system demands a high energy output, and the changes are often about fresh legs. Even in games, he hasn't moved away from his 3-4-2-1 shape at Old Trafford, so switching personnel tend to be about physicality or trying something different. His switches have often worked well.

But in North London last weekend, he was hamstrung by what must be the most inexperienced subs bench he has ever seen sat behind him. Victor Lindelof was the only one of the nine players to have played for the club before, and he hadn't been featured for two months.

The other eight players were yet to play for United, and the inexperience on the bench was more remarkable. In the end, Amorim waited until stoppage time to bring on 17-year-old striker Chido Obi, who didn't get a touch of the ball on his professional debut.

Amorim should have a little more experience available to him this weekend. Leny Yoro and Christian Eriksen should be back from illness, and Manuel Ugarte and Toby Collyer might have a chance of recovering from the knocks that kept them out of last weekend.

But he will still be without Amad and Kobbie Mainoo, and some youthful attacking reinforcements will need to be on the bench. Chido Obi will surely be
