I was among those who supported his move to Tottenham last summer. It wasn't a question of talent; I'm generally lenient with players, especially those in their first season – it's never easy. But I explained that it was his attitude and mentality that shocked me. The fact that he agreed to a move to Tottenham after just one season at a club like Manchester City under Guardiola made me doubt him and his ambition. I quickly realized he lacked ambition and wasn't willing to put in the effort to improve.
That said, once he stayed and extended his contract, I had no choice but to support him. But he absolutely must make an effort, particularly to learn the language, in order to integrate well into the group and build relationships with his teammates. It's unacceptable that after a year and a half here, he only speaks to Nunes in the squad. I suppose he can't communicate with the others because of the language barrier.
During training sessions open to the media, I observe him, and he seems like an outsider within the team.
I've read and heard many stories about players, each with their own personality, and some find match days complicated because they aren't happy within the group. But as soon as there's a new player of the same nationality or who speaks the same language, they've seen a radical change on the pitch, a significant improvement. That's why some agents say about players who fail at one club and succeed at another, "There are no bad players, only bad circumstances." I hope he'll make the necessary effort to at least learn the language to successfully integrate into the group.
