Morrison and the free-scoring Ings will be reunited at Turf Moor on the domestic scene after becoming acquainted as a part of Gareth Southgate's set-up earlier this month.
The enigmatic Morrison, touted as a future star during his time with Manchester United, has earned wide-spread praise of late after showing considerable signs of maturation at Upton Park.
Ings was certainly impressed with what he saw during training at St George's Park and is fully aware of the threat he is likely to pose his Clarets team-mates.
"He's got all the ability in the world; he's a great player," said the 21-year-old.
"On the ball he's incredible. He was really good in training, he scored some ridiculous goals as well, he's a good player."
The admiration clearly extends both ways, with Morrison praising Ings after his two goals saw Burnley past QPR as they extended their advantage at the top of the Sky Bet Championship table on Saturday.
"Danny ings is a very very good player," Morrison said on Twitter at the weekend.
The ex-Bournemouth man's brace against Rangers took his tally for the season to 13 goals in just 16 games and he continues to reap rewards in tandem with Wales international Sam Vokes.
Certainly Hammers boss Sam Allardyce, shorn of attacking options himself since Andy Carroll's injury earlier in the year, could look at Burnley's duo with envy as he presides over whether to persist with his much-debated 4-6-0 formation.
The form of the Clarets' front two has inspired them to eight straight wins in all competitions and Sean Dyche's men have extra reason to feel buoyant about booking a quarter-final spot on home soil.
Burnley have progressed in each of the previous 10 League Cup ties at Turf Moor and Ings expects the Hammers to be the 11th straight visitor to exit in East Lancashire.
"I'm sure we're going to beat them," he said.
"I'm really confident about that game. I'm sure with the confidence we've got at the moment we can turn anyone over. The crowd have been great getting behind us and it seems to be getting louder and louder."
