Psellos implies that though Romanos knew nothing of sultan's presence, he (Psellos) did know

Summary:
Romanos did not know (although Psellos says that he (Psellos) did) that Alp Arslan was with his army and responsible for most of their successes. [This claim is striking and hard to interpret. Does he claim that he knew at the same moment when Romanos did not? If so, he must have been somewhere nearby, e.g. at Chliat. Other possible explanations include a narrator's playfulness - the narrative is not ignorant of Alp Arslan's presence]
