Southampton are interested in signing Athletic Bilbao’s promising young defender Aymeric Laporte as they look to add to their defensive options in the coming transfer window.Saints manager Mauricio Pochettino is a keen admirer of the 19-year-old centre-back whose eye-catching performances for the Basque club have earned the interest of FC Barcelona.Pochettino is content with current centre-back pairing of Dejan Lovren and Jose Fonte but is not comfortable with his alternative options.Laporte is an accomplished technical defender and his ability with the ball at his feet is an attribute which appeals to Pochettino as he looks to take his Saints side to the next level.Athletic are currently on course to qualify for next year’s Champions League as they lie in fourth place, six points clear of nearest challengers Sevilla.If Athletic manage to qualify for Europe’s top competition, a move will be out of the question as the Basques will not be financially inclined to part ways with a key player.Super Sunday! Liverpool and Manchester City meet at Anfield + Swansea City face Chelsea at the Liberty Stadium for ONLY 9.99Read more Southampton transfer news.
