Former Wales manager Chris Coleman has been tipped to take over the hotseat at Swansea City.
According to former Wales striker Iwan Roberts, ex-Sunderland and Welsh national team coach Coleman is a name that has been linked with the vacant post.
"We're not sure who the manager will be next season, I know Chris Coleman's name has been linked with the club," Roberts told BBC Sport.
"One thing for certain, should Chris Coleman get the job, he would go into that changing room and shake things up because as someone from Swansea, he won't be happy with what's been happening at the club."
Swansea are yet to officially confirm that Carvalhal will not be in charge next season.
