What the England team needs now and has needed for the last 15 years is a coach with a clear strategy. The new manager needs to pick a system that suits the players and then decide on the best players for that system. They need to forget about trying to fit everyone in, you're never gonna fit 5 in form strikers into a team.
For example, I could decide to base the team on the most naturally talented attacking players we have: Oxlade-Chamberlain, Sturridge and Sterling imo. Put Wilshere at number 10 to release them and stitch them together and then have Henderson, who is a workhorse, and Dier to protect the defence to complete the midfield three. This is a possession based system where Ox would have freedom to come inside to add an extra body to midfield for control while Sterling is told to hug the line to give balance to the shape.
Or you could decide our players are too shit and Wilshere is a shit no. 10 and they're all injury problems on legs and we need to just accept we're a team with little talent. But we do have flying full-backs such as Walker/Clyne/Rose who don't know how to defend so why not use a 5-3-2 with Smalling, Cahill and Stones in defence. Stones can be the ball playing CB from the back and fire balls up to Kane and Rashford. Alli and Henderson to support box to box and feed on knocks downs while Dier anchors the midfield.
Whoever the new coach is, they need to break hearts and stop trying to fit Kane, Sturridge, Vardy, Sterling, Rooney, Alli and Wilshere into the same team. They need to decide what system suits the squad and drop the players that don't suit the system.
