BARCELONA (Reuters) - Wissam Ben Yedder's hat-trick for Sevilla in Saturday's 4-0 win at Real Sociedad was the latest demonstration of the Andalusian club's ability to find players from under the radar and mould them into top talents.

Ben Yedder, a former France Under-21 international, came to Sevilla from Toulouse with the task of replacing Kevin Gameiro, who departed for Atletico Madrid in the close season for 32 million euros ($33.69 million).
