Luis Suarez says he is 'disappointed because everything is not that it seems' following Liverpool's 2-1 defeat at arch-rivals Manchester United.
The striker was starting at Old Trafford for the first time since he finished an eight-match suspension after being found guilty of racially abusing Patrice Evra in the reverse meeting between the two clubs back in October.
However, Suarez was again at the centre of controversy when he refused to shake Evra's hand during the traditional pre-match routine.
The snub was reportedly the catalyst for a tunnel bust-up between the two sets of players at half-time while Evra celebrated wildly in front of Suarez at the final whistle.
Suarez, who scored Liverpool's consolation with 10 minutes to go, was labelled a 'disgrace' by United manager Sir Alex Ferguson, who also suggested the Uruguayan should not play for the club again.
The former Ajax forward has taken to Twitter in the aftermath of the game to express his disappointment at the outcome of the match.
He wrote: "We lost and we are sad because we have made a big effort... Disappointed because everything is not that it seems..."
Rio Ferdinand refused to shake Suarez's hand following the Evra snub and appeared to take a nasty tumble during the opening minute of the game as all three players went for the ball.
The centre-half confirmed there is no lasting injury and he also praised the United fans for their support during the game.
Ferdinand wrote on Twitter: "What a atmosphere what a game, great result. My neck feels ok, thanks for the concern people! Great support from our fans again!"
