The Brazilian superstar was seen swapping shirts with Leipzig defender Marcel Halstenberg at the full time whistle in Lisbon.
European football’s governing body introduced strict ‘return to play’ protocols for the Champions League and Europa League last month to ensure the two tournaments could be completed safely.
The 31-page document outlines extensive health and safety measures including regular testing, dedicated zones for players, staff and media within the stadiums and the wearing of face masks. Also included in the protocols was advice on shirt-swapping, which stated that “players are recommended to refrain from swapping their shirts”
The 28-year-old may also be forced to self-isolate for 14 days to guard against the risk of possible infection, which again would see him sit out Sunday’s game.
That has understandably got fans of the French champions concerned, as they contemplate the prospect of their side being without their talismanic forward for one of the biggest matches in the club’s history.
Prior to his shirt-swapping transgression, Neymar was inspirational as PSG breezed past Leipzig 3-0. The former Barcelona forward’s clever flick teed up Angel Di Maria to score PSG’s second goal, after defender Marquinhos had headed Thomas Tuchel’s side into an early lead.
Neymar also twice hit the post as the Ligue 1 side dominated their Bundesliga opponents, before Juan Bernat sealed the victory early in the second half.
