Football commentators on TV telling us what's happening when we can see it with our own eyes, as in:
"The cross coming in..." (Yes, we know it is)
"And he's pulled his shot wide" (Oh yes, so he has! Thanks for explaining!)
"His header goes over the bar" (No need to tell us)
"OOOH it's hit the post!" (Thanks. I thought it had struck an invisible force-field)
Your job is to identify players and explain anything that's not immediately obvious, plus the odd intelligent comment. Like referees, you should let the game flow - as Barry Davies did so well.
And don't smother us with non-stop factual irrelevancies, a la Tyldesley or Motson.
