Porto playmaker Fabio Vieira is interesting Bournemouth.
Vieira, 20, has played for Porto's youth sides for years and also been a regular in the national teams.
He is now becoming a key player in his country's Under-21s.
Porto are expected to start Vieira before the end of the season, which restarted last Wednesday.
He was an unused sub in the 2-1 defeat at Famalicao but has been the star of Porto's B team with seven goals this campaign.
Howe wants to pounce now rather than wait for Vieira to make the grade and then become priced out of his reach.
