In match football betting. What to look for?

[newteech]

Hi I'm new to betting live football. Could you give me some advice?

What might you notice during the match that might make you think a goal was on its way soon?

What might you notice during the match that might make you think --- ugh, this is gonna be a draw.

Thanks and please provide any other insight!

I have heard that players exhibit certain body language when they think a draw is going to happen. Agree/disagree?

Sometimes certain substitutions can signal a draw is happening?
