The former Paris Saint-Germain and Chelsea boss, Mauricio Pochettino is expected to take over at Stamford Bridge and could even be unveiled this week.
But Pochettino will wait until the end of the season to begin working with the squad, leaving caretaker manager Frank Lampard in charge until then.
Chelsea have spent almost £600m on new signings under Todd Boehly but Pochettino wants to make at least three more additions this summer, according to the Daily Mail.
It is claimed the 51-year-old is keen to sign a new goalkeeper, central midfielder and striker during his first transfer window at Chelsea and will favour players with Premier League pedigree.
This would appear to be bad news for current Chelsea shot-stoppers Kepa Arrizabalaga and Edouard Mendy, who have received criticism during their stints in west London.
Mauricio Pochettino also wants to sign a midfield partner for £107m signing Enzo Fernandez amid speculation N'Golo Kante could leave Stamford Bridge this summer.
Chelsea's need to sign a new striker is clear to see with Kai Havertz operating as a No. 9 for much of this season and Pierre-Emerick Aubameyang flopping since his move from Barcelona.
Romelu Lukaku, who also cost Chelsea more than £100m, is set to return from his loan spell at Inter Milan this summer but the Blues could decide to cash in on the Belgian forward.
While Mauricio Pochettino already has an eye on potential incomings, he will also need to offload several players, not only to trim Chelsea's bloated squad but also to raise some funds.
The Argentine is said to be impressed with the talent at Stamford Bridge but keen to bring more experience to a club who are just 11th in the Premier League following a dismal season.
Chelsea lost their first six games under club legend Lampard, who replaced Graham Potter last month, before picking up a much-needed 3-1 win over Bournemouth on Saturday.
Lampard said: 'I'm happy. We came in off the back of a tough run, it's been a tough year and there is a lot work to do.
"But the performance and the result in isolation are really good, we deserved to win the game. It's a nice step forward for the lads."
