Arsenal and Real Madrid ended last season with plenty of room for improvement – one manager has his feet under the table, the other is hoping he still has his magic.
Emery got some things right in his debut season at the Emirates, but he made some errors which he will hope to rectify this term.
He came close to qualifying for the Champions League, but his quest – both domestically and in Europe – failed.
Madrid meanwhile were someway behind Barcelona in La Liga, but have spent big to overhaul the Catalans in Spain and once again reign over Europe.
But what should fans keep an eye out for at FedEx Field?
Gareth Bale named in the squad
Bale is clearly not part of Zidane’s plans and the Frenchman has made no secret of his desire to see the Welshman find a new club.
Rumours this week of a move to China, possibly on loan, gathered momentum before Bale’s agent dismissed any thought of a switch to the lucrative league.
All this means he could feature in America tonight and it will be interesting to see whether he cuts an uninterested figure or puts in a virtuosos performance.

Gabriel Martinelli watch
Arsenal’s £6m signing from Ituano has already hit the back of the net in pre-season.
Pierre-Emerick Aubameyang and Alexandre Lacazette were the source of the vast majority of the Gunners goals last term.
An injury to either of them would have been a worry, but Martinelli has shown signs that suggest the double act could become a formidable trio.

No Casemiro – room for Pogba?
Zidane will be without Casemiro as the Brazilian enjoys an extended break following his country’s success in the Copa America.
He often acts as the destructive force in midfield that allows those around him to grab the limelight.
But will his absence tell, or will it in fact suggest there is room in this Los Blancos team for Pogba?
The two perform differing roles, but if Madrid can cope without Casemiro there may be added reason to pursue the Frenchman.
Arsenal’s youthful width
It has been a long time since Arsene Wenger became famous for giving the kids a go in the domestic cups.
There we saw glimpses of what good work the Arsenal academy was doing, but with Reiss Nelson, Emile Smith-Rowe and Eddie Nketiah all in the squad we may be afforded a look into the future.
Arsenal have chased Wilfried Zaha this summer and there is every reason to suggest that pursuit is not over.
But if one of their academy graduates can show Emery his much sought after winger is right in front of him then the Spaniard may be on to a gem.
What’s Emery’s shape?
The former PSG boss chopped and changed when it came to deciding on Arsenal’s formation last term.
He flirted with three at the back before reverting to a back four and toyed with playing Lacazette and Aubameyang through the middle together.
Each system enhances some players, but also hinders or fails to get the best out of others.
Emery needs to decide on what formation best compliments this Arsenal team and his players, but whether he divulges any of his plans tonight remains to be seen.
