Sunderland winger Sebastian Larsson insists the team have learned from their 4-0 defeat to West Brom.
The Black Cats have been transformed under manager Martin O'Neill, moving from the drop zone into the top half of the league.
Sunderland returned to winning ways on Saturday following a 1-0 win over Liverpool, but two weeks ago they were humbled by the Baggies.
Ex-Birmingham man Larsson insists the team know what they need to do and that they have learned from their Hawthorns drubbing.
"We know what we have to do to be successful. Since the manager came in, we have had one reality check and that was away to West Brom," explained Larsson.
"We said then, 'Let's not repeat that', and so far, we haven't. If we work as hard as we did today and last weekend, we know we are a good team.
"We know we can win games and we have beaten some big teams here now, and we feel very close to them."
Sunderland were without Lee Cattermole, Kieran Richardson and Stephane Sessegnon for the visit of the Reds and Larsson believes the trio were missed.
"It's obviously disappointing missing them, they are three very good players and they have done very well for us," he continued.
"But the manager said before the game, 'Let's not worry about that, let's focus on whoever can play and what we can do'.
"We were desperate to get the three points today and we are more than happy that we got them."
