Goalkeepers not allowed to touch the posts before a penalty kick?
Why? Are they getting some unfair "Luck" advantage?

On the whole seems reasonable but the goalkeeper one is odd. So, if they do touch the posts or do not have a foot on the line, what happens? Are they yellow carded, sent off?

The drop ball automatically back to the last team in possession - is that back to the goalkeeper of the last team in possession or at the point where the game is stopped?

Are the rules yet clear on the use of and when to use VAR?

In the end it is all a matter of opinion whether these measures alone will improve the game as a spectacle and cut out bad decision making by officials. There are many other issues that could have been addressed as well but have not been.

Let's give sin bins a chance, 15 mins off for a yellow. Taking one for the team should be an automatic red as should diving in the 18 yard box.

I think the posts include the crossbar and is to stop keepers from bouncing it and putting the taker off.

Nothing ever put Rickie Lambert off! Legend!

Firstly, we have to thank Charlie Austin for the early introduction of VAR.
His disallowed "goal" that led to his TV outburst came onöly days before the Prem. Chairmens meeting , and everyone saw the inequality of the incident . Historically, Saints have been the victim's far more often than the culprits.

As for the new rules. Most of them seem sensible - if applied correctly by the officials.
But the "handball " or, is it "arm" situation seems open to interpretation. What happens to defenders who use this to stop a potential goalscoring chance - is it a red card .or ?

I see I'm not alone in being baffled by the goalkeeper /posts ruling. (?) Why?
AND no-one has come up with a solution for those "diving incidents" (take note Deli Alli)
IF a player goes down at the slightest touch from an opponents - is that "diving" ?, recalling that there were TWO incidents involving Bertrand in the MU game last season.
On re-run you can see that either (or both) might have resulted in penalties on another day - with another ref. .. had it not been at Old Trafford.

Still not clear about the dropped ball ruling?. If it goes back to the last side in possession, what happens if it was near the opposite goal ?...sound sunfair to give them an advantage . Might it be used as a sort of "Free-kick situation" ?. or must it be punted back to the other teams goalie ? ....or ?

I recall the story from an infamous FIFA meeting back in the 1960's, when they were worried about the "goal drought" in football, and a French official was laughed to embarrassment when he innocently suggested... that the goals should be made wider ...
Considering we have 6'6" + goalies nowadays, it might be worth consideration.

NOTE; physical development; diet and training have increased enormously in the last 50 odd years. When I started watching football, (1959) ..the average height was around 5' 8" and anyone near 6 feet tall was considerd to be "a giant ".
