New Chelsea head coach Frank Lampard insists he will give the likes of Danny Drinkwater a chance to resurrect their Stamford Bridge careers.
Lampard returned to Chelsea on Thursday as he signed a three-year deal to replace Maurizio Sarri at the helm.
The former England international enjoyed a 13-year stint in west London, lifting 11 major honours and becoming Chelsea's all-time record goalscorer.
He has now been brought back in after just one season as Derby manager, where he guided them to the Sky Bet Championship play-off final.
Lampard will be working under a transfer ban for the first two windows of his tenure and is expected to use Chelsea's academy products more than other recent Blues bosses.
He has also hinted he may turn to players like Drinkwater, who did not play a minute of football last season other than as a second-half substitute in the Community Shield, and give them a clean slate.
"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 when asked if someone like Drinkwater would get a chance to impress.
"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."
Lampard's first game in charge is a friendly clash with Bohemians in Dublin on Wednesday, while his first competitive fixture at the helm is a trip to Manchester United on the opening weekend of the Premier League season.
