Manchester United had a little more of the game but created nothing in the first 20 minutes.
Wolves also did not manage to make any major danger even if they went straighter on goal and at least got some numbers in the closing column.
Among other things, a good shot by Ruben Neves who forced David de Gea to a rescue.
When the time passed half of the first half, the teams managed to come to their respective ends.
Wolves' Romain Saiss nodded a ball that took in the top of the crossbar, and shortly afterwards United's Cavani got a decent chance with the header.
34 minutes into the match, Manchester United put themselves up 0 - 1, as Bruno Fernandes finished off a strike from the left with a real cannon placed at the far post.
However, goalkeeper Rui Patricio made a fantastic save.
Five minutes later, United goalkeeper David de Gea saved a cross from Romain Saiss on a hard-hitting free-kick from the right.
Iskalla
United had quite a lot of ball at the beginning of the second half but the team did not manage to create anything.
When an hour had passed, it was rather Wolves who took over and got a couple of second chances.
Both teams, however, were icy cold in the last third.
When there were chances, it was offside.
In the 70th minute Cavani had his goal ruled out for offside and a few minutes later Wolves' Romain Saiss was close to scoring, but he also went offside.
With 81 minutes played, Wolverhampton's Rayan Ait Nouri almost extended the lead, but his shot from the left glanced off the top of the bar to fall behind the net.
After 92.55, United's Marcus Rashford got the ball inside Wolves' penalty area.
He pulls a shot that touches Romain Saiss and enters.
1-0.
