Anyway, if the head coach and the owner are not involved with any issues then surely the coach will get good support from the owner. That way, recruiting new players might be easy to do but yes, it still has to balance their finances as well meaning it doesn't need to be too extravagant. Also, Pochettino is not new to the Premier League so it will be easy for Pochettino to build the Chelsea squad, of course to get his best form next season. At least, even though maybe it's not so perfect, but with Pochettino I'm sure Chelsea won't fall outside the top ten in the standings.
Chelsea crisis have lingered so long and this is realy affecting the club and what you pointed out as the over-involvement of the club owner/manager is what have limited the multiple coaches who have worked on Chelsea without any possible and positive results that will change the face of the club in this season and the previous seasons.
The possibility of Chelsea building a foreseeable team is high if the club owner could give the coach a free hand to put up a good and formidable team that can take the club to win the championship.
