5 talking points as Greenwood scores for much-changed Man Utd in Young Boys draw

A much-changed Manchester United side were held by Young Boys at Old Trafford but still topped their Champions League group.

The Swiss team beat the Red Devils earlier in the season and may feel as if they should've left Manchester will all three points.

Mason Greenwood opened the scoring within ten minutes courtesy of a brilliant volley from a Luke Shaw cross.

Ralf Rangnick was able to ring the changes and named a completely different XI to Sunday, but the home side still started with plenty of intent.

United spurned opportunities to double their lead with Amad Diallo and Jesse Lingard unable to convert a good opportunity.

They were then made to pay as Fabian Rieder seized on a loose pass to fire a thunderbolt past Dean Henderson into the top corner.

Young boys were able to create numerous changes in the second-half, but failed to take them.

Rangnick handed a debut to Charlie Savage whilst his father Robbie commentated on his arrival on BT Sport.

The home side had scored late winners in games against Villarreal and Atalanta at Old Trafford, but were unable to repeat the feat once more as they shared the spoils.

Here are five talking points from Old Trafford.

1 Mason's claim

It seemed as if he was playing a different game at times. He is probably the player most unlucky to miss out in the win over Crystal Palace on Sunday.

Greenwood scored in the opening three games of the season, but has seen his goal output drop since then.

His finish for the opener though was that of a player flooding with confidence.

There has been a debate as to whether the 20-year-old should play on the wing or as a centre-forward.

Rangnick played him through the middle and he will have done his chances of future involvement no harm, even if his second-half performances, much like his team's, did drop off.

2 Ralf true to his word

The German named a whole new XI for his second game at the helm. For the most part, his first line-up was as you would expect, with the possible exception of changes at full-back.

His second starting XI though included plenty of youngsters and those who've seen their game time limited.

Rangnick said he would give all his players an opportunity early in his tenure and he has done exactly that.

Lingard and Donny van de Beek were handed starts, as were Anthony Elanga and Amad.

A new manager means players can start with a clean slate - and Rangnick has certainly come in to Old Trafford with an open mind, prepared to take his squad at face value with little regard for how they were treated or perceived by the previous regime.

3 A sign of the job

Rangnick rang the changes and will have been impressed with what he saw initially.

However, after Greenwood's opener and several missed changes, Young Boys began to grow into the contest and that trend continued.

The Swiss side missed several second-half chances which will have dealt Rangnick a reminder of the job he has on his hands.

The German started well at the weekend, with his ideas and style of football immediately evident in the win over Crystal Palace.

However the performance at Old Trafford, albeit with a much changed side, will not have filled Rangnick with optimism.

Young Boys were by no means the sternest opposition United will face this term and he will have hoped the likes of Donny van de Beek, Lingard and co would've perhaps done more.

4 The next generation

Rangnick named a host of academy stars on his bench on Wednesday night.

The established names, like Ronaldo and Marcus Rashford, were given the night off with the next generation handed a chance to experience a European night at Old Trafford.

Among them were Charlie Savage, son of Robbie.

Rangnick ended up turning to five of the seven substitutes which included Savage, Zidane Iqbal and the 35-year-old Tom Heaton.

5 Top dogs

Now that United have finished top of their Champions League group attention will turn to the last 16 and their possible competition.

Rangnick and his players have a lengthy break between now and the resumption of Europe's elite club competition.

But they will be keeping a keen eye on the draw, which takes place on Monday.

Finishing as group winners means that, theoretically, they should enjoy a more favourable draw.

Atletico Madrid are among their possible opponents in the next round.

PSG, Benfica and Inter Milan are also in the runners-up pot, as are Sporting Lisbon, who are led by the United-linked Ruben Amorim.
