He's at the Euros at the expense of Sandro Tonali, whom he ratted out.
He not only betrayed his friend Tonali, but he hurt his national team's chances of going far in the Euros, as Tonali is clearly a superior player who would have helped Italy perform much better than they will in Germany.
Fagioli is a terrible human being and a mediocre footballer. But that's the thing with mediocrity, isn't it? By definition, such individuals feel threatened by talented people, and they undermine and sabotage them to protect their own positions.
I wish Modric's last contribution to football is breaking this rat's legs.
