"We are very disappointed because we felt we had enough chances to win the game in the first half," said Aurelio.
"We lost a great opportunity to try to get closer to Manchester United but we must bounce back now and beat Sunderland at Anfield on Tuesday night.
"I thought we started really well. We kept the ball and had good opportunities but we couldn't score, and when that happens there is always the chance the opposition can score.
"Unfortunately we conceded a goal from a corner which was hard to take.
"In the second half we didn't create as many chances but we still had some good opportunities.
"Middlesbrough got every man behind the ball and made it difficult for us. They scored the second goal from a counter attack when we lost the ball, so that was disappointing.
"We will still keep on fighting because we know in football that anything can happen. We won't give up and we will now try to win every game."
