Star striker Zlatan Ibrahimovic was on Wednesday named in an initial 35-man Sweden squad for the Rio Olympics in August.
The squad will be whittled down to 22 players in mid-July, with only three of those squad members to be born before 1993.
Along with Ibrahimovic, 34, the enlarged squad includes only two other players currently featuring at the European championships in France: defenders Victor Lindelof, 21, and Ludwig Augustinsson, 22.
Coach Hakan Eriksson said the problem he faced was being able to find clubs ready to release players for the August 5-21 Olympics.
“It’s a headache, extremely complicated,” Eriksson said.
“Some clubs say yes, others no, and others have not yet decided.”
Ibrahimovic is out of contract with Paris Saint-Germain after four seasons in Ligue 1, but is yet to commit to a new club, although Manchester United are rumoured to be favourites to seal his signing.
