Liverpool risk losing promising midfielder Rafael Camacho this summer after contract talks stalled, according to Sky sources.
The 18-year-old is out of contract at Anfield at the end of next season, and reports suggest he is attracting interest from a host of top clubs in Europe.
The Portugal U20 international left Sporting in 2013 to sign for Manchester City, before he then joined Liverpool in the summer of 2016 on a four-year deal.
He made his senior debut for Liverpool in the 2-1 FA Cup third-round defeat to Wolves in January on the back of strong performances for the club's U23 side.
Camacho went on to make his first Premier League appearance as a second-half substitute in the 4-3 win over Crystal Palace later that month.
