You just have to decide which are goals, subs, cards and injuries. The first 2 look like yellow card + home goal combo.. Or it could be yellow card + injury, then player subbed off at 48'. You never know. this is actually quite fun lol
Don't think any are subs, subs show as arrows on and off.
Agreed, arrows to either side on the same minute usually mean a card and a free kick resulting in a goal.
