Ratcliffe dismissed rumors suggesting Ten Hag is at risk of being fired during his press conference before Manchester United's important Premier League match against Aston Villa on Sunday.
But the 71-year-old's downbeat assessment of United's predicament was hardly encouraging for Ten Hag as he fights to save his job.
"I don't want to answer that question. I like Erik. I think he's a very good coach but at the end of the day it's not my call," Ratcliffe told the BBC on Friday.
Ten Hag's side are languishing in 13th place after winning only two of their first six league matches.
They suffered a dismal 3-0 home defeat against Tottenham last weekend and blew a two-goal lead in their 3-3 draw at Porto in the Europa League on Thursday.
United's struggles have piled pressure on Ten Hag, who only survived a woeful eighth-place finish last season after Ratcliffe and his advisors conducted an internal review into the Dutchman's turbulent two-year reign.
Ratcliffe reportedly spoke to former Bayern Munich and Chelsea boss Thomas Tuchel about the United job during the review before opting to keep faith with Ten Hag, who had masterminded a surprise FA Cup final win over Manchester City in May.
But the British billionaire, who took charge of United's football operations after buying a stake in the club in February, was more equivocal about Ten Hag on Friday when he was pressed on his manager's travails.

Insisting any decision on the former Ajax boss would be made in conjunction with United's new sporting director Dan Ashworth and chief executive Omar Berrada, Ratcliffe said: "It's the management team that's running Manchester United that have to decide how we best run the team in many different respects.
"But that team that's running Manchester United has only been together since June or July. They weren't there in January, February, March or April -- Omar and Dan Ashworth. They only arrived in July.
"They've only been there, you can count it in weeks almost. They've not been there a long time so they need to take stock and make some sensible decisions.
"Our objective is very clear, we want to take Manchester United back to where it should be, and it's not there yet, obviously. That's very clear."
