West Brom, who finished 10th in the Premier League last campaign, have exceeded everyone's expectations this season, picking up 33 points from 19 league games and the Baggies currently find themselves sixth in the table, a mere two points off third placed Chelsea.
Although United, currently seven points clear at the top of the table, are the form team in the league at the moment having recorded eight wins in their last 10 league games, Evans has urged his team-mates not to lose focus when they take on the Baggies, a team he claims can trouble anyone on their day.
"We can't take anything for granted," Evans told the official Manchester United website.
"I remember a couple of years ago West Brom drew with us 2-2 at home [in October 2010] and it was a tough game.
"We played them towards the end of last season and found that they were a really hard team to break down.
"What they do is they get the two defensive units really tight. It forces you to go wide and try to get crosses into the box.
"They are very hard to break down."
Evans also highlighted the importance of getting the first goal of the game on Saturday.
"Once we got that first goal last season, it set us on the way [to a 2-0 win]," Evans added.
"Had we not got that goal we might have found it difficult so that could be important again this time."
United will be boosted by the return of Ashely Young and Danny Welbeck, but talismanic striker Wayne Rooney will miss out due to a knee injury.
