Yeah Barnes did not feature loads in the World Cup because Robson changed his formation half way through and had to lose a winger playing 5-3-2 and Robbo did get an injury against the Dutch. Was a regular in the qualifiers though when England played 4-4-2 and for most of Robson's time as manager, so he was in more often that he was out.
Yeah but all excuses aside, Barnes didn't play leaving Beardsley as the sole Big Four regular after Robson dropped out.
Never mind the qualifiers, Robson also used Steve Bull, Steve Hodge, Neil Webb etc regularly.
I'm talking about the World Cup of 1990, that's the last time England was truly unified behind all the players.
