The 27-year-old made headlines during the World Cup after celebrating his victor for Switzerland against Serbia by crossing his hands to imitate an eagle, which appears on Albania's flag.
Liverpool have left Swiss worldwide Xherdan Shaqiri out of the squad for Tuesday's Champions League tie at Red Star Belgrade, saying they were uncertain over what sort of reception he would receive in the Serbian capital.
Jurgen Klopp and Liverpool have decided against Shaqiri traveling with the squad due to the reception he may get in Serbia's capital city due to his Kosvan-Albanian heritage.
On the Red Star game against Liverpool, Nicholas said, "This is a volatile situation so not taking Xherdan Shaqiri they're trying to diffuse the situation".
Klopp considered the local politics when he took a pragmatic decision to leave the player at home to ensure their visit remains a "football story".
Shaqiri plays for Switzerland's national team but has roots in Kosovo, a former Serbian province that declared independence in 2008.More news: Term elections 2018: Trump makes final bid for votes
"They'll be hoping to use that to their advantage but we know if we play at 100 per cent again then we believe we've got the qualities to get the three points that we need and hopefully quieten the crowd".
Liverpool boss Jurgen Klopp said on the club's website on Monday: "It's a situation where we will go to the fantastic city of Belgrade as a football team to play football". We want the focus to be on a great game of football, free from anything else.
Red Star are winless in their last five games in European competition (D3 L2), losing the last two in a row while conceding a combined 10 goals (1-6 v Paris Saint-Germain and 0-4 v Liverpool).
"So for that reason, he is not involved and he accepts and understands this".
Red Star are bottom of the group on just one point and have virtually no chance of qualifying for the knockout stages ahead of Liverpool, Napoli or PSG so coach Vladan Milojevic has admitted they are playing for pride this evening. He's our player and he will play a lot of games for us but not tomorrow.
