Often overlooked, Spain's defense is thriving at Euro 2016 (The Associated Press)

SAINT-MARTIN-DE-RE, France (AP) -- Spain's often overlooked defense still has an important role to play at the European Championship. Spain enters Tuesday's final Group D game against Croatia trying to defend a 14-game unbeaten run at the European Championship. The defense has also helped by scoring an important goal in the opening match against the Czech Republic, when central defender Gerard Pique came through with a late header after the strikers had struggled to find the net.
