The coach doesn't need to strengthen any bond between those players you mentioned as alot of them will be sold or loaned before the transfer window ends. Already Aubameyang is going to continue his football at Saudi Arabia and other Chelsea players will be following him out of the door. Fofana would be sold or loan as there are rumors of Chelsea wanting to sign a striker who isn't going to be our first choice striker which means we'll likely get two strikers coming in before the window closes. Pulisic who be sold as well. Sterling still has some quality in him and can be utilized very well under Pochettino and that's the only player available frolm your list.

There's no doubt we have to strengthen the bonds of the new players we'll be signing in this summer window and that's what preseason are for. Todd Boehly got some millions in his bag to use in buying players Pochettino wants because he's getting alot of profits from the Chelsea players getting interest from the PIF of the Saudis. Already the likes of Kante, Mendy, Hakim Ziyech, Koulibaly are already on their way to Saudi Arabia as those deals has been finalized and Havertz is going to Arsenal as well with Mason Mount leaving to Manchester united.
