U2 are due to play a special gig for Radio 1
U2 have admitted they fear contemporary heavyweight bands such as The Killers and Coldplay.
The Dublin quartet, who are set to return with their first album in over four years, said they are constantly looking over their shoulder at their possible rivals.
"In our heads that's who (Coldplay The Killers) we're up against," said frontman Bono.
"You've got to keep an eye on the youth."
Despite the competition, the singer, who last week joined both bands onstage at a special War Child concert in London, hailed their hunger for success.
"Coldplay are such an extraordinary band with such song writing talents," he enthused.
"I think he (Chris Martin) is one of the most important melodists since Noel Gallagher, since Ray Davies since Paul McCartney. He's in the line of great British melodists.
"I love the fact that The Killers want to get their songs on the radio too."
Current chart toppers Kings Of Leon, who toured with U2 on their recent Vertigo world jaunt, came in for special praise from guitarist, The Edge.
"They are taking a southern American idiom and moving it into the 21st century," he told Zane Lowe.
"It's so great. We saw it on the tour, they were learning so much and they were so hungry to see what was going on.
"I think they're a band to watch for the future."
Bono also said that despite their own global success during a career which spans 33 years, the Dublin quartet are "constantly fighting for our lives" to keep people interested.
"A lot of people have a U2 album. Why would they want another one is a very good question?" he added.
"We have to fight very hard to explain why we think it's worth coming along for the ride with us. That's how we feel."
U2 are currently in the UK for a special week at the BBC, which will culminate in a one-off performance for Radio 1 on 27 February.
The group's 12th studio album, No Line On The Horizon, is released on 2 March.
