Reds manager Brendan Rodgers splashed out £8.5million to take Coutinho to Anfield from Serie A giants Inter after the midfielder rejected a late offer from Southampton.
A diminutive playmaker at 5ft 8in, some have suggested the physicality of English football may not be to the Brazilian's liking - but Pascoe is adamant his mentality will help him cope.
Pascoe said of the 20-year-old starlet: "He has played a lot of games from a young age. What we have got there is a young talent who has played a lot for Inter Milan and Espanyol.
"He is a young lad but what we have seen of him he can handle this type of pressure and he will be a good asset for us.
"The young lads who have come through have been absolutely brilliant but he has a lot of experience.
"He plays wide left, he can play as a number 10, and he likes to take defenders on and has a great awareness of his team-mates.
"He has to sort a few things out in Milan but he'll be back next week and he'll be ready to start straight away and he will be a great addition to the squad."
A persistent hamstring injury prevents Coutinho from making Liverpool's squad for Sunday's trip to face Premier League champions Manchester City.
