The Reds are back in action at the Theatre of Dreams on Thursday night, taking on Aston Villa in the third round of the Carabao Cup, following away games at Real Sociedad and Villa.
The 1-0 win over the Hammers provided a perfect illustration of backs-to-the-wall defensive work in the closing stages, in a bid to keep the clean sheet and secure three points, and Maguire admits he and Martinez were in their element.
Maguire will hope to return to action in the cup tie, having been on the bench for the Premier League loss at Villa Park, and he previewed the game in United Review, the official matchday programme.
