I agree we have zero chance of winning the CL next season or the year after. However a few years ago I said that we had zero chance of winning the Premier league again ever. The possibility took years to achieve but it is now possible.
As far as the CL is concerned we should aim to get out of the group, thus improving our points total and helping us get better draws in future. If (and I know it is a massive if ) we can carry on qualifying, continue to improve, and with extra finance from playing at new WHL then who knows what is possible in the future?
