Alonso, successfully started this season in the Chelsea, was in the starting line-up of the Spanish team, which was recently led by Luis Enrique. For the national team defender of the "blue" debuted in March, when he went on to replace Argentina in the match (6: 1).
On Saturday, Alonso made his debut in official matches for Spain - 58 years later, when his grandfather, Marcos Imas, held his second - and final - match for the Spaniards at Wembley (2: 4).
In 1981, the father of the defender of the "blue", Marcos Pena, held his first of 22 matches for Spain, which in that meeting at Wembley proved to be stronger than the English.
"A pleasant coincidence," - that's how Alonso noted the fact that his grandfather and father also made their debut in the official matches for Spain at Wembley.
"I'm very proud. This is something that I will be able to tell my children about in the future, but now I'm just concentrating on the next game ".
"My father played the first game for the team at Wembley.
He told me all the stories about this when I first played here, and it's also something special for my family ".
Alonso is the first Spaniard who continues the football traditions of his family, when three generations of players stand for the national team. In total, seven such cases are known in which three generations of players from the same family competed for the national teams, including in the cases of Javier Hernandez (Mexico) and Diego Forlan (Uruguay).
