Keane was in the Sky Sports studio as United put in their best performance of the Premier League season so far, in the first Roses derby in the top tier in 16 years.
The Old Trafford side won 6-2 against Marcelo Bielsa's super attacking Leeds to go third in the table, though it wasn't something either Scott McTominay, who scored twice, or Solskjaer were thinking about.
However former United captain Keane felt the pair should be looking at the league table and predicted his former team could pose the biggest threat to Liverpool in the title race, and are just five points off the champions with a game in hand.
Keane was in a unusually jovial mood and even managed to joke that McTominay's new haircut was the reason for the Scot's excellent performance.
The 24-year-old rocked up to Old Trafford with a new trim on the weekend, and promptly scored twice in the first three minutes to set Manchester United up for a 6-2 thrashing of their fierce rivals.
A brace from Bruno Fernandes, and goals from Victor Lindelof and Daniel James completed the rout, with Liam Cooper and Stuart Dallas grabbing the consolations.
The Red Devils played well as a team to put away Marcelo Bielsa's side, but McTominay was singled out as the man of the match and Keane had some kind words for him afterwards.
"Scott McTominay is maturing," the Old Trafford legend claimed.
"I really like him. I even like his haircut, I think his haircut has made him sharper.
"It was the perfect game for him. I do like the look of him."
Keane wasn't the only one to praise McTominay, with manager Ole Gunnar Solskjaer very happy with the midfielder and the team overall.
Football fans were also pleased with the youngster, comparing him to several legends.
Manchester United go into third in the Premier League after the win, six points behind leaders Liverpool but with a game in hand on the Merseyside club.
Solskjaer will be particularly happy with the change in fortunes after some fans had turned on him following the Red Devils crashing out of the Champions League earlier this month.
