Real Madrid is not allowed to wear their famous whole white strip when they take on Arsenal in the first stage of their quarterfinals of Champions League on Tuesday evening.
The side of Carlo Ancelotti, who touched in London on Monday evening prior to the enormous collision at Emirates, will have an all-gray kit against the Gunners alternatively and use their third strip for the season.
Given the chance, Real Madrid would probably have chosen to wear the iconic white shirt, as they have already done in different road games, including their dramatic victory over penalties in Atletico Madrid in the final round.
Jude Bellingham and Co also wore white away from Brest in the group stage.
While Arsenal goes into the showpiece of Tuesday as the home team, the Gunners priority they would like to wear.
It is not surprising that the side of Mikel Arteta has chosen to wear their home shirt, which is mainly red with white sleeves and shorts.
According to UEFA's rules, the species of a team, as well as their shirts, should not clash with the colors of their opponents.
As a result, Real Madrid is unable to wear completely white because the shorts would be collided with those of Arsenal.
Los Blancos was given the option to wear their Orange Away kit, as they did against Manchester City in the Etihad earlier in the competition, or their All-Grey Strip.
The Gunners go into the crucial collision against Madrid with a substantial shortage of 11 points on Liverpool in the Premier League title race, while they are also out of the FA Cup.
The Champions League, a competition that the club never won in their history, now presents the best chance of Arsenal on silverware between now and the end of the season.
But the men of Arteta will first have to surpass Real Madrid in the quarterfinals, who have won the Champions League six times in the last 12 years.
Arsenal fans will be happy with the return of Sterrenman Bukayo Saka, who has made two performances since the international break of March when repairing his long-term hamstring injury.
Although Saka is expected to start in what a determining game marks in the Arsenal season, Arteta will certainly be without crucial first-choice defender Gabriel Magalhaes, who is for the rest of the campaign with a hamstring tear.
Gabriel Jesus, Riccardo Calafiori, Takehiro Tomiyasu and Kai Havertz also remain due to injuries for the Gunners, while Raheem Sterling serves a ban of one match.
Arsenal attracted 1-1 with Everton in Goodison Park in their last Premier League match, while Real Madrid arrived in the back of a 2-1 defeat against Valencia in Laliga on Saturday.
