Swansea are reported to be among the clubs tracking Barcelona forward Sandro Rodriguez, who is heading for the exit door.
Rodriguez has just over 12 months remaining on his current deal at the Nou Camp and the Spanish champions have yet to offer him a new one, leading to reports he will be allowed to leave.
There will be no shortage of interest in Rodriguez, with Tottenham, Crystal Palace and Everton also said to be keen on bringing him to the Premier League ahead of next season.
Swansea are in need of more firepower after struggling for goals last season, and at least one new striker is said to be high on the wanted list of boss Francesco Guidolin.
Eder has already headed for the exit door, while reports are rife that Bafetimbi Gomis could also move on following a disappointing goals returns last season.
