Despite picking up a point away from home, the Uruguayan claimed that he was unhappy with the result and said that his team deserved more.
"Am I happy with the point? No," he told Sky Sports News.
"It should have been more because we were the better team. We deserved to win the game. We didn't get the breaks with the shots or penalties, we got nothing.
"From the first minute we passed it well but you need to take your chances. We will be having shooting sessions in training, I don't know how we haven't scored."
The Black Cats are still bottom of the Premier League.
