Chelsea ace Eden Hazard is full of praise for Tottenham's Belgian duo.
Hazard, 21, was quick to praise his countrymen Mousa Dembele and Jan Vertonghen ahead of today's clash.
He said: "Dembele is a big player; I think he is one of the best players in the league at this time and it is difficult to defend against him.
"He has great pace and good technique, and is very effective in the centre of the pitch.
"I follow all the Belgian players in the Premier League, and now he is at a bigger club with better players it will be good for him."
The Blues ace added: "Normally Vertonghen is a central defender and not a left-back but he can play both. He is very good technically and likes to bring the ball forward out of defence."
