In the post-match press conference, our Portuguese head coach revealed that the plan was for Shaw to be removed during the second half, in the same way that Casemiro, Harry Maguire, Kobbie Mainoo and Noussair Mazraoui were.
Thursday's huge Europa League semi-final first leg against Athletic Club loomed large over the planning for the preceding Premier League game, according to the boss, with Ruben acknowledging that some players' minutes had to be controlled with that challenge in mind.
But such was the way that the game developed, and Shaw's influence within it, that Amorim explained that Luke had to be kept on the pitch to aid us in the search for a positive result.
