But the signings of Dimitar Berbatov, Mladen Petric and Kieran Richardson have given the Cottagers a boost.
The west Londoners currently lie ninth in the Premier League and Senderos, who has missed out with a foot injury, has been impressed by his team-mates.
He said: “It has been a pretty good start and we’re really happy with it.
“Hopefully we can build on the good start and continue like this.
“We’ve lost a few players and replaced them with players who are hungry and want to do well.
“The team has responded really well in the first game and hopefully, for me personally, I can get my chance and grab it.”
