STOCKHOLM -- Sweden coach Erik Hamren on Wednesday promoted six players from the team that won the European Under-21 trophy last year to the 23-man senior squad he's bringing to the European Championship in France next month.
Goalkeeper Patrik Carlgren, defenders Victor Nilsson Lindelof and Ludwig Augustinsson, midfielders Oscar Lewicki and Oscar Hiljemark and Celta Vigo striker John Guidetti were key players in the U21 team that beat Portugal on penalties in the final.
Guidetti will be competing with Marcus Berg of Panathinaikos and Emir Kujovic of Swedish champion Norrkoping for a spot next to Zlatan Ibrahimovic in Sweden's attack.
"I know I'm up against good players but I've got confidence and believe in myself," said Kujovic, the Swedish league's top scorer last season with 21 goals.
At 27, the Yugoslav-born striker has made only three senior appearances for the national team.
Sweden beat Scandinavian rival Denmark in a playoff to reach this summer's tournament. Hamren's squad will face Ireland, Italy and Belgium in Group E.
Apart from Ibrahimovic, Sweden lacks big stars and looks to the U21 players to infuse the squad with the energy and fighting spirit.
"We are aiming to advance from the group," Hamren said. "But we have to perform at 100 percent. We have to be realistic and see that we are the lowest-ranked team."
He said midfielder Albin Ekdal is in doubt after being injured over the weekend in a night club accident but was included in the squad anyway.
The Hamburg player wrote on Twitter that he stumbled and fell backward onto a table and had to be hospitalized with cuts to his back.
"I will do everything in my power to play in Euro 2016," Ekdal said.
