Having been on fringes in recent times, Carvalhal is sure of handing the former Bristol City player more chances - due to Wilfried Bony's season-ending injury.
“Tammy Abraham is an interesting player,” Carvalhal told club website.
“Wilfried’s injury will give more opportunities to him and he is someone we believe in a lot.
“We liked him last season when he was scoring a lot of goals in the Championship. He has quality, a lot of pace and he is a good finisher.
“He is a very good talent and we will try to help him give the maximum to the team.”
The youngster has been training since his return from injury and Carvalhal hopes he can add a new, but tasking dimension to his game.
“He has only been training with us for something like a week and a half after injury,” the Portuguese added.
“He must learn and he knows he must learn, especially in the transition to defence. He must be strong, but he can do that because I have seen him do that.
“When he does that, he will be a more complete player. We believe he will progress with us.”
Abraham's return of four goals - in 20 English Premier League matches - is only bettered by Andre Ayew [five goals] in Swansea's squad this season. And the Chelsea loanee is set to return to action in Tuesday's FA Cup fourth-round replay against Notts County at the Liberty Stadium.
