La Liga champions Barcelona are keeping close tabs on Hector Bellerin and Joao Cancelo, Sport can reveal.
The Catalans are aware that starting right-back Dani Alves could decide to leave in the summer transfer window and they want to be prepared should that happen.
According to Sport, their former player Hector Bellerin is the number one candidate to replace the Brazilian, but the problem is that Arsenal are not ready to negotiate his sale.
As a result, the Catalans may turn their attention towards Valencia full-back Joao Cancelo, who has shown a great deal of potential since joining from Benfica.
The 21-year-old did well to nail down a regular starting berth this season, going on to make 28 La Liga appearances, scoring one goal.
Cancelo appears to have done enough to catch the eye of Barcelona scouts and he could soon be the subject of an official bid from Camp Nou.
