Chelsea defender David Luiz has no doubts over the expected impact of Tiemoue Bakayoko.
Blues fans are anxiously waiting for the former Monaco midfielder's debut.
Luiz told SFR Sport: "Baka is a special person, a little one who has great humility. I say small because he is 22 years old when I am 30 but he's a monster.
"I hope he can do the same thing as in France. He was great in both the league and the Champions League. I hope he will adapt quickly to the English championship.
"It's a little bit different in intensity. He will see that there are monsters like him physically. But he's a great guy, who's always working well."
