Fans arriving early for the match said they are hoping for a peaceful event.
Muslim friends Ansheed Tahir, 24, and Mazin Mohammed, 23, who are students from Upton Park, east London, said they are worried after Friday's events but are determined to attend to show their sympathy for the French.
Mr Tahir said: "We have had the tickets for two months and have not been put off by what happened.
"I am looking forward to the minute's silence and a chance to show solidarity with the people of Paris."
His friend added: "This has not affected us as Muslims. People in Britain are good to us. Globally there is blame for the Muslims but it is a tiny minority who are doing this and we do not approve of violence - it is against our religion."
The stadium bore the words Liberte, Egalite, Fraternite in red, white and blue and the arch over the ground was also lit in the colours of the French flag.
