Thomas Tuchel has said he selected Kepa Arrizabalaga in goal against Newcastle as he wants to allow the goalkeeper to find some rhythm.
The Spaniard was reportedly one of the reasons why Frank Lamopard was sacked, with the former Blues boss not convinced by Kepa and so elected to sign Edouard Mendy last year.
Mendy has conceded only once in four games since Tuchel took charge, an own goal following an error from Antonio Rudiger, but he has been dropped - with Kepa retaining his place after keeping a clean sheet in the FA Cup win over Barnsley on Thursday.
