He and his agent played us so we reward him by pretending nothing happened? Not playing him for the rest of the season is the most satisfying act of revenge and it will definitely hurt his chances of getting that big signing bonus and decent salary.
It is not about rewarding him anything, it is about salvaging something out of his last 6 months here while being paid by us handsomely.
As much as we dislike him and his snaky agent, we are a professional club and we don't have scores to settle with him. We don't need revenge, that is some silly kids' game. Especially now getting the Spanish players union involved and having them issue statement to support Dembele, all because of our distant wish that he would just pack his bag and leave now?
He will be training with us and we will play him later, you bet. It won't hurt his chances of getting a signing bonus at all, that's exactly why he is not leaving right now. He doesn't want his future employer to shell out any money to pay us, he is saving them every penny so he can get rewarded.
