Among the Euro's 24 teams only Croatia can get closer to Spain in terms of midfield quality. Luka Modric and Ivan Rakitic are the Twin Engines.
Modric plays alongside a central defensive midfielder that takes away from him all the defensive duties, therefore he only has to worry about distributing the ball.
Barcelona's man Rakitic, has a different role with the NT. He has more offensive involvement and usually is played behind center forward Mario Mandzukic.
The squad has gained much balance with the inclusion of a central defensive midfielder that relieves the twin engines from defensive duties. Sometimes it is Badelj sometimes it is Kovacic.
Vintage. Almost 20 years ago in France 98, the croatian golden generation of Prosinecki, Boban, Vlaovic, Suker, Jarni, Stimac and Boksic got to the semifinals of the Worlc Cup. The curent team is the most talented one since then.
Inter Milan's Mateo Brozovic and Ivan Perisic will play on the wings supporting Mandzukic on the attack.
Both teams have faced three times, and Portugal has won all of them. In England's Euro'96, the score was 3-0.
