Nope. I think he did it just right. He talked back in a fiery game, which I love to see from a young player. He wasn't taking crap from no Roma douchebags.
For a while, it was a worthy time-killing strategy even.
Then the tackle? I could never tell a striker not to do that ... that was awesome. Bring mooooar.
His red card was completely unjustified, and he held his cool despite Manolas going all mental on him.
I think he's just fine as he is.
