Espinoza believes the anti-climax of his non-appearance for Latics against Bournemouth on Saturday could turn out to be a blessing in disguise in the long-term.
"I was ready to play but, at the same time, it might turn out to be a good thing that I didn't get on," Espinoza told the Wigan Evening Post.
"I'd not even managed to practice for a full day with the rest of the squad, so it wouldn't have been ideal.
"Obviously if the circumstances had been different, and we'd been two or three goals up, it might have been a different story.
"But it wasn't to be and it's meant I can spend this week further acclimatising myself into the club ahead of the Fulham game."
