The idea of seeing Pepsi as being preferred by Muslims to Coke isn't unrelated to the actions of Israeli Zionist against Muslims in Palestine and the invasion of the country by Israel since its creation.

It is seen as a means of silent protest due the economic ties between US and Isreal with Coke being an American company.

Although Pepsi is also an American company and the protest also affects them in a way, Coke is more prominent, especially after it opened its franchised plant in Israel in the 1960s and its assumed continuous support of Israel's terrorization of Palestine.

Pogba's reaction during that press conference at the Euros may have been due to this.
