It may have been a sofitsh penalty but you could say the same as the foul that led to their goal.
Also the Danish defenders were clumsy, (that one reason why we paid a lot of money for Wan-Bisska, he has his limitations in some areas of his game but the timing of his tackles and his ability to take a ball cleanly without touching the opponent are the best in the world.
I initially thought the penalty was given for the contact with the Danish number 5's foot on Sterlings right foot. Not sure it was though, However there was contact on Sterlings right knee not his right foot. Then there was contact on sterling left hip.
Also there was contact a 1/2 second before on Sterling by the number 5 and sterling didn't go down. It was 2 clumsy challenges by their number 5.
You can also debate all day long if it was a penatly or not, or even debate it until next week, but im not sure its going to change much, the ref decided it was a penalty and England won the game 2-1.
You can also debate all day long if you would fall over with a similar tackle but there is no way of knowing for sure unless you test it out for yourself. Run at full speed then have someone make contact with your right knee and left hip and see if you loose balance or not. Post the video so we can watch.
