The Brazilian attacker is wanted by some of the biggest clubs in Europe and is reportedly inching closer to a move to Chelsea.
Leeds United had a close relegation battle last season and managed to survive only because of some of the key players in their squad.
Even Kalvin Phillips is edging nearer to a move to champions Manchester City.

He said to The Daily Mail: ‘They are going to have to do some recruiting themselves, Leeds.
‘That was a legitimate criticism (on Leeds not bulking up the squad). Bielsa liked to work with a small and thin squad. They got away with it last season.
‘But if you are a Leeds fan, you are thinking “blimey, our two star men are off. How are we going to stay in the Premier League next season?”‘
