Someone replied to the tweet with a picture of McTominay which I assume was taken today (fits with the other pictures of players coming off the bus). Don't know why the United photographers missed him.
Fred and Matic not accounted for but I'd be very surprised if Matic wasn't in the squad.
They replied again saying they've not seen either. Honestly, under Ole it has pretty much always been that the squad at the hotel is the squad who will be at Old Trafford for the match with no new additions so I'm going to assume there is no Matic.
I'd guess team would be something like:
De Gea
Wan-Bissaka Lindelof Maguire Shaw
McTominay Pogba
Lingard Mata Rashford
Martial
Subs:
1. Romero
2. Dalot or Young (we know it'll be Young)
3. Jones, Smalling or Tuanzebe
4. Andreas
5. Chong or Gomes
6. James
7. Greenwood
Would love it if it was Greenwood instead of Lingard or Mata.
