No it's not. Coppell had previously mentioned he fancied a break on numerous occasions. He felt he owed us something last summer and stayed on for one final season. It's all but certain he will take this break/retiremement this summer and go wish our best wishes.
Definitely urban myth !!
I'd agree that there is a good chance he may decide he's done his job here but I don't think there is any evidence that he 'decided' to stay for a 'final' season and the 'need a break' comment was very much a one off throw away. If he'd said it on numerous occasions he'd have gone last summer.....
