Ask yourself why is his foot so high,forget this crap about only having his eye on the ball.His foot was high because he knew the keeper was coming towards him,hence trying to lift the ball over the on rushing keeper.He had already see the keeper come out of the penalty area to head a clearence,he knew what was coming,the foot was high to stop himself being hurt in any collision between the two,and Marne wasn't,t going to come off the worse.He didn't,t try to head the ball because he knew he could come off second best,and he wasn't,taking the risk.
