I think that's a Kevin Keegan lineup - don't mind how many you score, we'll score more. Shaw and Walker are both too attacking minded to play in a back 3 - if you want to play a back 3 you really need 3 'proper' defenders. Shaw and Walker are best used as wing backs. No holding midfielder, and I actually think so many attacking players you're in danger of a 'too many cooks' situation up front. Sure, they're all excellent players, and wouldn't argue against any of them in the Euro squad, but not playing together.
Foden - Good choice. Kane - Hmmm - good at deceiving refs suppose. Rashford - after seeing Andy Robertson put him in his back pocket, it gave me cause for concern. Anyone that wants to do their homework on Rashford, would do well to watch the Manchester United v Liverpool game up until the 63rd minute.
