Southampton are reportedly continuing their pursuit of Braga midfielder Rafa Silva.
The 20-year-old is said to have attracted interest from the Premier League outfit last month.
Now, it has emerged that manager Mauricio Pochettino sent more scouts to watch the Portuguese player in action against Sporting Lisbon at the weekend, according to The Mirror.
Silva, who has scored nine goals in 20 appearances this season, is said to also be a target for Bayer Leverkusen and Sevilla.
