Patrice Evra, Luiz Suarez Saga Today, Who Was Wrong?

Before today's match between Manchester United and Liverpool at Old Trafford, the spot lights were on Patrice Evra and Luiz Suarez.

Suarez was banned for 8 matches for racially abusing Evra. Suarez's match today was his first after his match ban.

But during the traditional pre-match handshake by players, Suarez refused to shake hands with Evra.

At the end of the match, ended 2-1 in favour of Man U, Evra celebrated in front of Man U fans and in front of Suarez.

Was Suarez wrong with his pre-match handshake refusal with Evra? Was Evra also wrong with his post match celebration?
