Marcelo Bielsa's outfit are searching to end a 16-year absence from England's elite, and Championship bosses have been high in their praise across the campaign after playing the Whites. Here's what some of them have said out United's promotion hopes with 10 games to go...
1. Jonathan Woodgate (Boro)
"If they get in the Premier League, it'll be some train to get on, it'll only go one way. I've been there. It's an incredible club."
2. Danny Cowley (Huddersfield)
"They won't fall short this season. You look at his team, you can see it, you can feel it, he's got them under remote control. They are in a very strong position."
3. Slaven Bilic (West Brom)
"Us and Leeds. Its much easier to be in the shade and nobody is talking about you, but still I wouldnt swap with any of the teams that are below us."
4. Lee Bowyer (Charlton)
"I think they go up. I think they were unlucky not to go up last year. I thought they were the best side last year - nothing's changed."
5. Grant McCann (Hull City)
"I think they're a Premier League team... they're a top team, I've no doubt they'll probably go and get promoted this year."
6. Mark Warburton (QPR)
"Leeds are very talented. After what happened previously the focus is very much on them. [Marcelo Bielsa] is an outstanding manager, they're a talented team and on May 3, I'm sure they'll be right there."
