Dunno really. Some decent, progressive football would be nice. World Cup in Brazil will be very tough, but I'd like to see us go toe to toe with some of the bigger nations for once. Seems like every time we play someone decent we give up 65% possession, play on the break and/or rely on set plays. I think we have the quality to do more.
Beyond that, just build a decent footballing team and see what happens. Obviously difficult to know who'll be in the team in 4 years and what the competition will look like, but generally speaking we have the talent to be looking at semi's or better in every European championship imo.
