The 1-0 loss at home to Aston Villa on Saturday means the Black Cats have won just one from their last 17 outings in the league, and have as such dropped to 16th position.
However the 24-year-old is convinced the team will fight back, suggesting they have the calibre of players to climb up the table, while indicating they will certainly stay united.
"As a team, we are absolutely devastated, but we are definitely sticking together," he told reporters.

"There are going to be points that need to be made, but that's football. No-one is happy to be losing games, but hopefully we are going to win more than we lose this year.
"We believe in the team we have. There is too much quality in that dressing room for us not to turn this around.
"Before Saturday, we had only been beaten at Manchester City. A lot of pressure was put on the team due to the fact that we were not scoring goals, but we were still picking up points.
"We have just got to keep working hard, keep moving on and the quality is going to come through in the end."
Martin O'Neill's men face a tough trip to Everton in their next match, but may feel they can pick up some points in the following ties against the likes of Fulham, West Brom, QPR and Norwich.
