Antonio Conte admits Romelu Lukaku will be dangerous against Chelsea, but won’t change him for Costa.
Lukaku struggled to get first team football at Chelsea and finally left after loan spells at West Brom and current club , Everton.
The Belgium international leads the goalscoring chart of the Premier League with 24 goals, while Costa has 19.
“I think Lukaku, for sure, is a really good player,” Conte told a pre-match news conference ahead of Sunday’s match at Goodison Park. “He’s scoring a lot of goals this season, but not only this season.
“We must pay great attention [to him]. But it’s always the same. We study the opponents and we try to find the best solution to stop them – for single players and about the team.
“We must pay great attention to Lukaku and the other players. They have a lot of good players, good technique, good finishing.”
Asked whether he would like Lukaku at his disposal, Conte responded: “In my team? As I said before, for me my players are the best in the world. I don’t change my players with other players.”
