Petr Cech wants Chelsea to sign another goalkeeper to drive him forward.
The Daily Express says since Carlo Cudicini was allowed to join Tottenham in January, Cech has only Henrique Hilario, who was originally signed as a third-choice goalkeeper, behind him.
Chelsea looked at Italian Marco Storari, 32 - currently at Fiorentina - in January and Cech is understood to be keen for the club to strengthen their goalkeeping department because he thrives on having pressure on his position.
"When you climb, you climb, you climb and you climb - and you have the momentum," said Cech.
