Watch United's second game in 24 hours!

The Reds conclude our pre-season programme against the Spanish side, and the match will be shown live on the United App, ManUtd.com and MUTV.

There are also a limited number of tickets remaining to see the game in person, but be quick to get yours!

Ahead of the Reds’ final pre-season test, here are the key talking points…

TEN HAG’S HOME DEBUT

The boss will sit in the Old Trafford hotseat for the first time tomorrow, casting a final look over his side before next weekend’s Premier League opener against Brighton at the Theatre of Dreams.

What’s more, it will be your first opportunity to see the newly changed home dugout, with United now sitting in the area closest to the tunnel, as opposed to the previous arrangement.

NEW SIGNINGS

Tyrell Malacia started in Oslo against Atletico Madrid, while Christian Eriksen came off the bench in the latter stages. Both of our summer signings impressed against Atleti and could be set to feature again tomorrow at Old Trafford.

Fellow summer signing Lisandro Martinez did not play against the Spanish giants, and will no doubt be eager to make an impact against Rayo in front of the United fans on Sunday.

Prior to kick-off at the Ullevaal Stadion, Ten Hag said: "We will see how the game goes but I have already said I want to get as many players as we can 90 minutes in their legs. Martinez and Eriksen are not ready for that just yet so we have to build them. They have to build their fitness levels but they will definitely get their game time today or tomorrow, or today and tomorrow.’’

Following the boss's comments, both Eriksen and Martinez remain in contention to feature in front of our supporters on Sunday. Make sure you don't miss it!

YOUNG REDS

During Tour 2022, youngsters such as Zidane Iqbal and Charlie Savage shone for United as we recorded wins over Liverpool, Melbourne Victory and Crystal Palace.

This fixture is an opportunity for you to see our young Reds star once more. Players such as James Garner, Shola Shoretire and Isak Hansen-Aaron are expected to get minutes against the Spanish side, and they will hope to make a lasting impression on Ten Hag.

FORMER REDS

Rayo have ex-United players Radamel Falcao and Bebe in their ranks. Falcao scored four times during his season-long loan with United in 2014/15, while Bebe was a Red between 2010 and 2014, making seven appearances and netting twice.
