Same for me. I am shooting for 2017 but might slip to 2018.
The American experience with sports stadiums is much different so take my thoughts with a grain of salt. (Many or most American stadiums are paid for by taxpayers because American taxpayers are idiots and billionaire owners threaten to move the team if they don't pay up.) My city, Washington, DC, built a stadium for its baseball team that opened in 2008. It is a fairly unremarkable stadium--it does what it is built to do without charm. They located it in an underserved neighborhood that was dangerous for many, many years but it is basically built on top of an existing subway stop. It was a bit of a leap of faith to come to the stadium in the first few years, but a solid redevelopment plan, initiated in the late 90s has completely transformed the neighborhood in the past 6-7 years. In 2005, I wouldn't have felt safe here--now, I live in the neighborhood. They've got plans to build a stadium for the local MLS team in a similarly underserved neighborhood nearby and I suspect it will, coupled with redevelopment money nearby, serve that neighborhood well.
Admittedly, my understanding of Liverpool geography and politics is very limited. I'd recommend the Washington, DC approach if a similar neighborhood exists.
And lastly, and this is probably heresy, but a new stadium for Everton probably nets 50 events per year if you count league and cup matches, concerts and other random events. If you can get the reds on board, you are looking at 80-90 events. From a developer's standpoint, 90 events bringing 50K people to the neighborhood per year is a lot better than 50 events. If we need city government support to get this done, building the biggest coalition possible is a good strategy.
