The BBC broadcaster called the Manchester United star “admirable” for sending romantic verse to his childhood sweetheart , which was revealed in a BBC documentary on Rooney earlier this week.
Marr said: “We haven’t actually seen that great modern Manchester poet’s work.
“What we do know is that he writes poems to Coleen and that is an admirable thing, I think everyone should write poems to their spouses, lovers, partners and children. I think it’s a very personal and direct way of communication.
“Wayne Rooney goes up hugely in my estimation when he does write poems.
“We share many things Wayne Rooney and I, we both have shaved heads and an ambiguous relationship with follicles but I’m a little less good on my right foot, or my left foot for that matter, but I’m delighted to know he writes poetry.”
The talk show host, who has written a book about British poetry, was responding to a question as he spoke at Cheltenham Literature Festival, where he repeatedly turned the air blue with the f-word as he recited poetry featuring swearing.
The BBC’s former political editor, author of We British: The Poetry of a People, also rubbished the majority of television programmes.
He said: “Most of the time you should watch less television, there is so much crud on so many channels.
“I work on television, it pays my rent, it puts food on my table and I’m very grateful for all of that but when people watch more television than they read books they’re in trouble.
“If you love poetry, if you love literature, if you love all that’s best in our culture read the bloody books.”
Marr also revealed he has between 2,000 to 3,000 poetry books in his house but his own “toe-curling” verse is so bad he will never share it with the world.
