The Black Cats travel to Manchester in search of their first win of the season, after what has been a dismal start to the campaign.
Sunderland were handed a relatively friendly fixture list, but have only amassed two points after six games, with defeats to Premier League new boys Bournemouth and Norwich City coming along the way.
On-loan Rennes striker Toivonen has shown promise, however, and grabbed his first goal for the club in Wednesday’s League Cup defeat to Manchester City.
The Swede has warned his teammates of the dangers of sitting back against United and wants them to be brave on the ball.
“To go to United away, you need to dare to play because if you just defend, defend, defend for 90 minutes then that is tough,” said Toivonen.
“If you do that, then you would need a lot of lucky bounces. United is always a very tough place to go, of course, but we don’t have any pressure on us.
“We need to go there and really work as a team.”
A result on Saturday would be as welcome as it is unexpected, but the manner in which City cut through Dick Advocaat’s team in midweek doesn’t bode well for their chances against the league’s top sides.
