Possibly part of a motivation talk for the younger players? From LR's last interview before being given the heave-ho it sounded like many of the youngsters felt that they had "done it" because they were playing regular first team L1 football. In a sense they have in that they have gone way beyond the vast majority of players and their peers at other clubs. However, this loses sight of the fact that they are playing utter garbage and the club is charging towards relegation and the ends of their professional careers. Perhaps the message was that they haven't come near to what Walcott has done, but that he is continuing to develop because he hasn't just gone "big money transfer to top club- check, member of England World Cup squad- check, Job done!" but rather now is starting the hard work to establish himself as a top player.
