Arsenal will feel as if they can conquer all after slaying the Champions League's final boss, but only a performance similar to the two they produced against Real Madrid will suffice when Paris Saint-Germain come to town.
This is PSG's second visit to the Emirates this season after losing 2-0 on the second gameweek of league phase fixtures. Luis Enrique's side failed to impress on that serene October night, but have since blossomed into a majestic juggernaut who have so far dumped two Premier League teams out of Europe.
PSG enter the bout with a full cohort of players available, while the Gunners are still without a host of key names. However, there have been a couple of fitness boosts ahead of the first leg.
Here's how Arsenal could line up for the start of their semi-final on Tuesday night.
Predicted Arsenal lineup vs PSG (4-3-3)

Goalkeeper & Defenders
David Raya (GK) - After an imposter tried to do his best David Raya impression (and failed miserably) against Crystal Palace last week, the Spaniard will return between the posts on Tuesday.
Jurrien Timber (RB) - Timber has had an excellent season, and he came to the fore in the quarter-finals. Vinicius Junior failed to reliably beat the sturdy Dutchman, who'll be put to the test by PSG's dribblers.
William Saliba (CB) - There have been a couple of lapses from Saliba in recent outings, and we can only hope the Frenchman has got all of the errors out of his system before this wonderful Parisian attack come to town.
Jakub Kiwior (CB) - Kiwior has been so impressive since Gabriel succumbed to a hamstring injury. He remains the weakest link in this defence, but the Pole has looked at ease alongside Saliba.
Myles Lewis-Skelly (LB) - Lewis-Skelly has relished the big occasions in his short senior career so far, and he'll likely see plenty of another teenager, Desire Doue, on Tuesday. The versatile French winger has been a sensation.
Midfielders
Declan Rice (DM) - Thomas Partey's suspension forces the boss into a midfield rejig, but the solution is simple. Rice will drop into a deeper role on Tuesday.
Mikel Merino (CM) - Merino trained on Monday and is expected to be fit for PSG's visit after missing the draw with Palace. The Spaniard is only improving in year one, and he was brilliant in midfield against Ipswich two Sundays ago. His physicality and box-crashing ability will be key here.
Martin Odegaard (CM) - The captain missed the October meeting due to the ankle injury which has compromised his campaign. It's been a tough season for Odegaard, who'll add some sparkle to a rugged Arsenal engine room.
Forwards
Bukayo Saka (RW) - Saka leads his duel with Nuno Mendes on points from their first tussle this season, and their battle could go a long way to deciding the outcome of this tie. Mendes, one of Europe's best left-backs, has locked up the likes of Mohamed Salah in the new year, and will be determined to bite back given what Saka did to him in October.
Leandro Trossard (ST) - Trossard played a major role in Arsenal's league phase win over PSG, as he mitigated Odegaard's void in the middle of the park. The Belgian enters the first leg in good scoring form, and has troubled defences with his movement from a fluid false nine function.
Gabriel Martinelli (LW) - The Brazilian winger got through plenty of hard work in the quarter-final, and he was eventually rewarded at the very end of the tie. Martinelli might not be everybody's cup of tea, but he's ever so important for the Gunners in Europe.
