Barcelona chief Robert Fernandez was at the Mestalla yesterday on a scouting mission.

Robert took in Atletico Madrid's exciting win at Valencia.

Sport says the subject of his attention was Los Che fullback Joao Cancelo

Barca have decided they will sign a new fullback in January, with Robert casting a wide net across Europe in their search.

Cancelo, 22, is rated in the €25 million class and could follow former teammate Andre Gomes from Valencia to Barca in the New Year.
