Haven't a clue mate, might be one for @Eggs to field
Was bored enough to try find anything about Charlton training himself to use both feet but I've either got the wrong player or I dreamt it as he says he never had to practice using both feet at all....strange is that because I have long compared Barkley to Charlton, indeed a long time ago I posted a montage of Charlton to illustrate what I meant. Barkley is much more Charlton than Gerrard.
Not sure about the right boot theory re Charlton but I have heard him recall how he got that fantastic shooting ability with both feet. Charlton said he painted a line about 4 ft off the floor on the wall of the Old Trafford car park, he'd then spend hours striking footballs keeping them below that line. Look back at the 66 World Cup goals and it's amazing how many were hit hard and flat at that height. Great player was Bobby Charlton.
Enjoyed watching a few clips though. It's definitely similar style to Ross with his upright running style and, deceptive pace. Great spring too and shots with absolutely no backlift. Think Ross bit more deliberate in his shooting but that might be something practice brings.
Don't see the Gerrard shouts at all. He's not really an athlete in that sense but much more close control. Still think there's a lot of Gazza about the way he runs right into packs of defenders and uses his technique and physique to draw them into mistakes. Much better now he's trying to stay on his feet.
