The band collaborated with legendary producer Brian Eno on their latest album
Coldplay say they won't be playing a one-off gig in the grounds of Knebworth House in Hertfordshire next summer.
The band hinted they were trying to book the venue last month but have told their own website that they haven't been able to get it.
On coldplay.com lead singer Chris Martin said: "We tried to get Knebworth but it just wasn't possible. So we're having to think of something else.
"In fact, I think we have thought of something else."
He added: "Hopefully we'll be able to announce it soon. And hopefully it's not the same day that Oasis have booked it."
Oasis are playing three dates at Wembley Stadium next July as well as dates in Manchester, Sunderland, Cardiff, Edinburgh and Coventry.
Chris Martin told coldplay.com: "It would be a great double bill. And we wouldn't mind opening.
"I would also, funnily enough, open for Take That. We were in the dressing room yesterday and, for whatever reason, we started singing Back For Good.
"We sang the whole thing, word for word, with all the right chords on our piano, without having to learn it or anything. It was great.
"So I'd like to use this forum, the Coldplay website, to announce that if Take That want us to open for them, we'll do it.
"The only problem is that we'll have to get down the gym for a bit."
