Jarrett joined the Foxes from championship rivals Preston North End last month and has revealed his relief at being offered an extension by boss Rob Kelly.
'I couldn't have asked for a better start to my time here. I am enjoying my time here and feel I am getting better. You haven't seen ths best of me just yet.' The midfielder said.
This news comes as the City squad prepare for the visit of west midlands outfit West Bromwich Albion and Jarrett will be hoping to fight for the cause and help Leicester to their first four consecutive wins since 2003.
Meanwhile, Rob Kelly has spoken out about his dissapointment at not bolstering the squad in time for tommorows Championship clash. Kelly had earlier suggested that he was planning to bring in some fresh faces from the Premiership but has so far failed to do so.
