First, is there even a rule that resembles what Dodo-eren is saying???
Second, If there is, Dodo-eren may have opened a can of worms. Because I'm pretty sure all sidelines have a bunch of smartphones on their sideline and a smartphone is basically a small laptop. (it is definitely "technology")
Not only is Dodo-eren a bad sport I can't believe that he even complained about the officials in the 1st half when all the calls went his way.
