I think it's great that some average old-timers have been left out and the likes of Oxlaide-Chamberlain, Sterling and Lallana..etc have been given a chance.
James Milner is a constant surprise to me, he really isn't a talented footballer but hey, Roy sees something in him as a "workhorse".
Generally we don't have much talent with a football so, in the absence of that, pace is a good substitute. We have pace for sure. Pace always gives you a chance.
Because we tend to give the ball away so much I think that will come back to haunt us in the Brazilian heat. South American/"Latin" countries will pass the ball around us, at walking pace, while we wear ourselves out trying to win it back..before promptly giving it back to them. We have to hope that, when we have the ball, our quick, youthful, front players can capitalise on any ageing defences.
I'm a Man U fan and hence should rave about Rooney. However I think he's been average at best for two years. He's culpable of losing possession too much. That's the #1 sin at this level.
Can he control his tendency to get frustrated and kick out? I suspect not when it's 100degC and he's lost possession again.
Overall though, you never know, pace up front, Ross Barkley in the middle, we may surprise some complacent teams.
I'd prefer to go out 3-4 than 0-0 and penalties.
