Following Manchester United's tour of Thailand and Australia, Erik ten Hag's men travel to Norway to play their penultimate pre-season fixture against Atletico Madrid.
It was three wins and a draw for the Reds, before they returned to Carrington to play a behind-closed-doors friendly against National League side Wrexham. A run out was given to the youngsters and United won 4-1, with new signing Christian Eriksen on the scoresheet.
This could be the biggest test of Ten Hag's side so far ahead of their Premier League curtain opener.
When and where?
United will fly to Oslo, Norway, where they will play at the Ullevaal Stadion, the national team ground.

It will be a quick turnaround for United, as they're against Rayo Vallecano at Old Trafford the following afternoon.
The 28,000 seater stadium should witness an interesting game, which kicks off at 12:45 BST. Full international kick-off times can be viewed here.
Expected changes in squad
With two games in two days and Diego Simeone's men being the first test, it's likely that we'll see two completely different teams from Ten Hag.
Advert
It has been widely reported that a stronger XI will be seen in Norway, while a weaker side will feature at Old Trafford.
This could likely mean that we see a similar starting line-up to what we've got used to in pre-season, with a front three of Marcus Rashford, Anthony Martial and Jadon Sancho spearheading the attack.
Although, the two new faces in Eriksen and Lisandro Martinez could also be involved after both getting minutes under their belt at Carrington on Wednesday.
It is more than likely that many of the team play full games as they look to enter their final gears ahead of the season's start date in less than two weeks.
What has Ten Hag said?
The manager has spoken on the tactical elements that will be in play against the Spanish opposition. With it being a different test to the games played thus far.

"We've played a different type of football, different systems and I think that will also be the case when we face two Spanish teams," Ten Hag told MUTV, speaking after draw against Aston Villa. "Again, a different approach and what we want is to play proactive football.
"We want to play with initiative, we want to play attacking football and that's also what we've seen today, but in the end, you have to control the game and that's what we didn't do. They [players] can have a lot of confidence because they are good.
"But they have to know they must work hard and we need to work as a team to have good performances. It has been incredible [pre-season tour], it was a really fantastic experience, we have so many supporters across the world.

"We know they are behind us, so may fans and we have to give back - we will work hard for that."
Ones to watch
This game will be another chance to see Martial and Sancho at work. The pair have been the two most exciting players for United in pre-season so far.
The Frenchman looks a changed player, whilst the summer signing of last year is looking like the player Red Devils supporters thought they were getting from Borussia Dortmund.

Whilst pre-season does not mean anything in the grand scheme of things, being able to improve confidence ahead of the new season could be pivotal, and this gives the talented pair another chance to do so against improved opposition.
Martial scored in each of the opening three fixtures under the new Dutch manager, assisting once against Crystal Palace.
Even though he didn't find the scoresheet against Aston Villa, his ability in the build-up was shown for Sancho's opener, when he helped circulate the ball from right to left before Sancho fired in from Luke Shaw's cross.
The Englishman will more than likely be the number one name on the team sheet going forward. Another chance to see his developing relationship with Diogo Dalot will be much anticipated by fans.
