Atletico Madrid have reportedly scouted Swansea City defender Ben Davies in recent months.
The 20-year-old signed a new contract at the Liberty Stadium in December, but that is not thought to have stopped the likes of Arsenal, Manchester City and Liverpool from monitoring his progress.
However, La Liga side Atletico are also in the market for a left-back during the summer and have been encouraged by Davies's performances for the Swans, according to the Daily Mail.
The Wales international only made his Swansea debut back in August 2012, but he has since gone on to make 60 appearances for the Welsh club.
