West Brom head coach Tony Pulis believes Louis van Gaal will be under pressure to ensure Manchester United are genuine contenders for the Premier League title next season.
United turned to David Moyes to replace legendary manager Alex Ferguson ahead of the 2013-14 campaign, but the Scot was dismissed less than 12 months in to the job.
"Louis has obviously spent a bit of money and brought quite a few players in, I think he has had a year to look at it," Pulis said ahead of West Brom's visit to Old Trafford on Saturday.
"The difference from himself and [Chelsea manager Jose] Mourinho was that Jose knew the league. This is Van Gaal's first season in the league. Next year he has to come close to winning the league, he'll know that.
"It's been great experience for him this year. I'm sure he'll add a few players to the squad next year. They'll want to win it, I see them getting stronger, I can't see them getting weaker.
"David didn't get it [time], but Louis has, most probably on the basis he has been successful at bigger clubs. He's won major titles at bigger clubs. He's earned it by what he's done elsewhere, that's a fact of life."
A 2-0 victory at Crystal Palace and a goalless draw with Liverpool moved Albion seven points clear of the relegation zone.
"We still need a couple of points and we have a tough run-in," he added. "We're underdogs in every game."
