Enzo Fernandez, Moises Caicedo and Mykhailo Mudryk are among the club’s biggest buys but while Pochettino insisted in July there is “no patience” in football, Hasselbaink has called for calm.
LiveScore ambassador Hasselbaink told the PA news agency: “Look, it is a project. Chelsea is a project and it will take time.
“You need to give time. They have a lot of players, a lot of talented players but they need to gel and that takes time. It doesn’t matter how much money you throw at it.
“The only way they will learn is by playing and having that pressure. You will see some of them will make it and be able to handle it, but some, as always is the case, they won’t handle the pressure. That is the nature of the beast.
“I do think Chelsea have bought well, really well with a lot of young players and the most important thing now is to trim the squad because there is still a lot of players.
“Then mould it and everyone can get to know each other.”
Hasselbaink reflected on Chelsea’s stuttering start to the season after being put through his paces by youngsters during a session put on by Bloomsbury Football, a grassroots charity who provide weekly football sessions for young people in London.
Bloomsbury Football are set to receive a £5,000 donation from LiveScore, who have launched a Life-changing Goals campaign to mark their 25th anniversary.
