Chelsea boss Frank Lampard says Michy Batshuayi will get a chance under him.
Batshuayi spent last season on loan at Valencia and Crystal Palace after struggling to make his mark following a £33.2m move from Marseille in 2016.
"Everybody who joins up tomorrow, and it will be staggered, will have the opportunity to show what they can do, their attitude, the way they play and train in pre-season onwards," Lampard said.
"I would be a fool to come here with ideas about 'I'm going to freeze anybody out'. I want to get the best out of the squad.
"Everybody has an opportunity. I have no pre-conceived ideas about anybody, I have got good knowledge of the squad but I need to see them over the next month."
