Marco Amelia was signed as cover following an injury sustained by Thibaut Courtois.
Manager Jose Mourinho decided to sign Amelia as cover in the goalkeeping department after a knee injury sustained to Thibaut Courtois earlier on in the season left Asmir Begovic deputising for the Blues in the Belgian's absence - with the Guardian reporting that Courtois is expected to return to action in December.
In a column for the club's official website, Cudicini said: "He is a very steady goalkeeper. He was a part of the national team when we won the World Cup in 2006. He has a lot of experience and has played for big teams which I guess is what Jose Mourinho was looking for – someone who can add to the goalkeeping department now Thibaut is injured, as cover for Asmir Begovic.
"He has plenty of experience in Serie A which is not an easy league to play in, especially with AC Milan. He knows what it is to be a part of a big club, and because of that he can always give confidence to the players playing in front of him. It was a no-brainer to sign him and I wish him well."
Judging by what Cudicini has had to say, it seems that Amelia is the perfect cover option for Chelsea, one that is very experienced but has no qualms about sitting on the bench after being out of contract prior to agreeing a deal at Stamford Bridge.
It's hard to say just how much game time Amelia will see for Chelsea. With Begovic playing every game since the injury picked up by Courtois, there could be an opportunity for him to impress in a League Cup tie against Stoke City on Tuesday, if Mourinho feels the need to ring the changes in order to freshen up his side.
Certainly, signing the Italian was something of an insurance policy, but it's one the club's ambassador seems pretty pleased with.
