Schwarzer's Fulham return blocked
Schwarzer is currently third choice at Stamford Bridge behind Thibaut Courtois and Petr Cech and hasn’t played competitively since May.
The veteran, who turned 42 earlier this month, spent five years at Fulham, making more than 200 appearances before leaving for Chelsea in 2013.
It is clear Schwarzer still holds the Cottagers close, following comments he made this week about the club’s owners, who he said had “ripped the heart out of the club”.
According to the Daily Mail, Fulham approached Chelsea about a potential loan deal, but the Blues declined the move.
The situation has sparked suggestions that Cech, who is currently number two, could leave in January.
Schwarzer made 13 appearances last term as Chelsea’s back-up goalkeeper, including playing in the Uefa Champions League semi-finals.
Fulham currently have goalkeepers Marcus Bettinelli and Gabor Kiraly on their books, but have conceded the most goals in the Championship and are experiencing a period of uncertainty.
Manager Felix Magath was sacked a fortnight ago after a poor start to the Championship season following last term’s relegation.
