Mikel Merino has once again become Spain's hero. The Navarrese player scored in the 91st minute the goal that gave the Spanish team qualification for the quarterfinals of the World Cup after an in extremis victory against Portugal (0-1). But he wasn't just the protagonist of the night on the pitch. After the match, the 30-year-old player, currently at Arsenal and trained at Osasuna before playing for Borussia Dortmund and Real Sociedad, explained the difficulties he has had to overcome to reach this point.
