Chelsea's transfer decisions are under scrutiny amid internal concerns over the club's £1billion recruitment drive.
Mauricio Pochettino is under pressure following a difficult first season at the club that leaves them languishing in 11th place in the Premier League.
His position is not believed to be under immediate danger, with the club's preference to see out the season before reviewing Pochettino's performance ahead of next season.
Pertinently, however, Mail Sport understands that if the club's season continues to deteriorate, then those plans could be brought forward.
But while the Argentine's performance is under review, the spotlight is shifting towards those in charge of player recruitment as the club identify factors behind their struggles despite spending heavily on new players.
