(Reuters) - Chelsea boss Frank Lampard said goalkeeper Kepa Arrizabalaga is the first to admit that there is room for improvement after making errors this season but he is satisfied with his work ethic.
Kepa saved a penalty in Wednesday's 2-2 Champions League draw at Valencia but came under criticism for failing to stop the two goals, especially the equaliser when he seemed to pull out of a save when Daniel Wass shot from distance.
