Once Chelsea's move for Gittens goes through, they will have added Gittens, Joao Pedro and Liam Delap to an already strong attack featuring Cole Palmer, Nicolas Jackson, Pedro Neto, Noni Madueke, Christopher Nkunku, Marc Guiu and Tyrique George.
It might feel like Chelsea are almost just doing deals for the sake of it, but there is a specific plan.
The signing of Joao Pedro is expected to add competition for the number nine and 10 positions, with Nkunku expected to leave.
Gittens will come in as a left winger and will replace Jadon Sancho after his loan spell from Manchester United was not made permanent. It's also worth noting that alternative option Mykhailo Mudryk remains provisionally suspended for a failed drugs test.
Delap comes in to add competition with Jackson in the number nine position, with Chelsea having looked short up front last season.
Chelsea are not forcing any of the players currently in the Club World Cup squad out but could accept substantial offers for Madueke or Jackson, who are not deemed untouchable like Palmer is at Stamford Bridge.
It's worth noting that Chelsea have seven attackers for four forward positions, but we haven't mentioned the likes of midfielders Enzo Fernandez and Andrey Santos, who often play as number 10s as well.
Meanwhile, the prospect of loaning out Guiu and George, both 19, remains open.
The pair played a substantial part in last season's Conference League campaign, but Chelsea need to strengthen the squad now they are back in the Champions League.
The likes of exiled attackers Raheem Sterling, Joao Felix and Armando Broja remain at the club and are all available for sale.
