Mikel Merino and Aleksandar Mitrovic were among the goals as Newcastle United’s internationals played their first round of games.
Merino scored a stunning goal – and set up another – in Spain Under-21s’ 3-0 friendly win over Italy.
The midfielder, signed on loan from Borussia Dortmund, took the ball on the edge of the box before nutmegging a defender and finishing.
Speaking after Newcastle’s 3-0 win over West Ham United last month, Merino said: “I’m looking forward to enjoy the time with my national team, to spend time with my team-mates and to learn and communicate with them.
“It’s a new generation, and I’m looking forward to enjoying this week.”
Technically-gifted Merino impressed against West Ham.
The 21-year-old said: “I like to give the passes to my team-mates, because I think it’s the best way to win matches.
“Precise passes, and to go forward, that’s what I try.
“Sometimes you misplace passes, because you take risks in order to give a good pass to someone in front.
“But when the pass is good, it creates a clear chance for our team, so I try to give these passes.

“If I fail with half of it, then it doesn’t matter, because I know the other half will be good chances.
“That’s what I try to do. I have to learn a lot from Rafa (Benitez), from the league,
“I’m only 21, and I think I have a lot of things to improve.
“But, by playing, I will learn and I will become a more complete footballer.”
Meanwhile, striker Aleksandar Mitrovic netted for Serbia in their 3-0 win over Moldova in a World Cup qualifier.
Mitrovic will miss Newcastle’s next three games through suspension after admitting a Football Association charge of violent conduct.
The 22-year-old elbowed West Ham’s Manuel Lanzini after coming off late in the game. He scored United’s third goal.
