We travel to Goodison Park having lost our unbeaten start to the season with a 1-0 Premiership defeat against United at the Lane last Saturday.
Everton have made a storming start themselves and sit proudly in third with just one defeat and five wins in seven games so far.
The Toffees are actually unbeaten since the first game of the season and include a goalless draw at United in that run. They've won their last three games.
"We've got Everton on Saturday and that will be equally as tough as United," said goalkeeper Robbo.
"They are flying, picking up points from everywhere and first of all we've got to go there and silence the crowd, be solid at the back as we have been and hopefully get a couple of goals at the other end.
"Everton's personel is the same as last season, they've brought in a couple of players and everyone was writing them off at the start of the season, saying they were in crisis when Rooney was on his way.
"But they've proved everyone wrong and it will be a very tough game for us.
"Every game in the Premiership is difficult, every team has good players and on the day anyone can beat anyone.
"Everton are on a good run of form at the moment so it will be particularly difficult to play them at Goodison Park, but we have to be confident."
Paul Robinson believes Saturday's trip to Everton will be every bit as tough as facing United last weekend.
