Sunderland midfielder Sebastian Larsson admits Stephane Sessegnon will be vital in the season run-in.
Larsson concedes they risk being sucked into the relegation battle.
He said: "Sess is massively important for us. Everyone knows what he can do.
"He can win you a game or create a chance out of nothing. He has looked really sharp in recent games.
"Hopefully, he will take that on and keep it going until the end of the season. We want him to be a massive player for us.
"With Sess, he is a guy you want to get on the ball. You want to get the ball to his feet and let him do his thing and try to open up some space.
"He found it tough sometimes when he was playing through the middle, but in the last few games, when he has been out wide, we have been able to give him the ball a bit more and with a bit more space to run into and attack teams.
"Let's just hope we can keep that going."
