Chelsea boss Antonio Conte is tightlipped on their pursuit of Everton striker Romelu Lukaku.

Lukaku featured for Everton in a friendly against Real Betis on Saturday although Chelsea are confident they have made a breakthrough in their bid to re-sign the Belgian international they sold two years ago for £28m.

"I do not want to speak about the players of other teams," said Conte, when asked about Lukaku.

"This is not respectful to the club or to their players. I prefer not to speak."
