Simon Grayson was disappointed to lose a 3-1 half-time lead and felt his side didn't get the rub of the green at Brentford.
The game finished all square as a disputed free-kick and a deflected effort saw the Bees pull level in the second period.
“We responded well to going a goal down early to a soft goal against – I thought Lee Cattermole was fouled in the build-up when we had the ball,” he said.
“To lose a 3-1 lead is disappointing. When you're in that situation you want to see the game through.
“The second goal was very close to being a good tackle by Didier. I think he got the ball and then we're disappointed to see it in the back of our net.
“We responded well again, didn't buckle too much and were asking questions on the counter attack. Then the third goal's a huge deflection.
“When you get 3-1 up you want to win the game, but it's three games unbeaten so the glass is half-full and we'll look to build on it next week now.”
Sunderland now play three out of their next four games at home, with a double-header against Bristol City and Bolton next up.
“Six points is the objective, of course it is,” Grayson added, whose side also face Millwall after a trip to Middlesbrough.
“We need to build on the last few games, and performances to a certain degree.
“The focus is three points on Saturday and then we will move on to the midweek game.”
