What makes you say that happened, and what makes you believe he wasn't? Sorry, the battering this kid is getting in some parts here is fudging embarrassing.
Wow, I don't even know where to start. But of all the posts criticizing Sterling, you chose this one. Ok. You call Sterling, a year younger than Kane, a kid - as he is the only one I have "battered". Also ok. I stand by my assumption that some players looks to be more eager to score/impress than to win. I would call Sterling one of them, when you time and time and time again choose the hardest option rather than passing the ball. In several cases to Kane, who albeit a "6-season wonder" is a proven goal threat and the main attacker. If you find this notion "fudging embarrasing", that's entirely up to you. But enough of that.
What makes me say that I think Saka chose to take a penalty, is that if a player don't want to take one because he feels he's not up to it - or not "old enough", only an idiot would make him take one anyway. I don't think Southgate is an idiot. From that, I deduct that Saka volunteered, and both Southgate and the players who against their better judgment didn't take a penalty, let him. Including those who may be at least one of: 1. more suited. 2. older and more experienced. 3. aware of the fact that Saka has not taken a penalty neither for club nor country. And again, at 19 you're old enough to vote. You're old enough to drive a car and have kids. You're old enough to bank millions upon millions by playing football. I'm more impressed by even playing for your country in front of gazillions than kicking a ball from 12 yards, as kicking a ball is what I consider a significant part of football and players at international level should have at least some basic training at it. But then again, I'm quite easily impressed. And you're old enough to be a hero by scoring in a shootout. Still, when you take a penalty, from what I would assume not dragged by the ears kicking and screaming, there's a possibility that you may miss. Not only can you hit badly, but there's often a top class keeper doing everything in his power to stop you from scoring. A footballer should be aware of this. Two inches to the right and Rashford would be a hero. If Saka was indeed forced against his will, then I would say that Gareth is not a very nice man.
Finally, at no point have I slated Saka for missing the penalty. At no point have I ever slated anyone for missing a penalty, as long as it's not due to arrogance, lack of concentration, stupid run-ups or a combination of those. I've simply stated that 19 is not too young to take one. And that missing a penalty is just as much a part of the game as scoring one. Someone has to miss - if that wasn't the case, history's first shootout would still be ongoing. If, for arguments sake say Grealish, had taken the penalty and scored, would Saka be old enough to take no. 6? Or 7? Or any of them except the 11th and last one, that I would presume Pickford would have taken? Would any of those penalties have involved less pressure? Would he be let off this huge task with a written note from his mum?
