Speaking with Sky Sports, Keane said [via The Daily Mail]: "I hope he's given more time and they get to the summer, they can regroup and restructure the club, or whatever that might be.
"There's huge problems at the club. But I hope he's given a chance to get things right. Because last year there was some positives, we have to be honest with that. And they have an FA Cup final coming up, and if they manage to beat Man City, it's going to be very, very difficult, but there's huge challenges he's facing, and he's under huge pressure."
Rooney was also of the same opinion, however, agreed there are chances of Ten Hag being shown the door: "I personally hope they do give them time. Because I think there's a lot of problems. Recruitment is massive, and it hasn't been good enough throughout the year.
"So I do think it takes time to do it right. But what we've seen before, I was part of [Man United's team] in the FA Cup final, when we won in 2016 and Louis van Gaal lost the job so you never know."
