These days, Petr Cech often takes the field looking more like Batman than he does a goalkeeper.
At the age of 29, Cech should be approaching some of the best seasons of his professional career, but a bad error at Wigan in December has caused some people to suggest he's a player in decline.
I don't believe that to be the case, as all goalkeepers go through rough spells in their careers that can affect their confidence and ultimately their performance.
Cech may look vulnerable at the moment, but Chelsea are a team in transition and he can't rely on his defence to help him through it right now.
Whether Andres Villas Boas thinks Cech is a weak link remains to be seen. Just in case, however, let's take a look at some possible replacement goalkeepers who could one day become good enough to don the Chelsea shirt.
