Costly missed the 2010 World Cup through injury but the Real Espana winger looks set to start Brazil 2014 in fine form, having scored a goal in Honduras' 4-2 loss to Israel on May 31 - his sixth in eight matches for his country.
Espinoza, who plays for Wigan in the Championship, told his club's website Costly is 'a match winner' as he discussed some of Honduras' key players ahead of the World Cup finals.
"He (Costly) is a match winner with an undoubted goal scoring record for Honduras and a crucial member of our squad," Espinoza said.
"Some people might know a bit about him because he played in England for a short time but he could catch our opponents off guard.
"Carlo is a big, strong guy with lots of experience across different leagues and he can be a real handful for defences.
"He missed out on the last World Cup with injury which was a real shame and hopefully this time round he'll make his impact."
