Croatia defender Vedran Corluka says that reaching the World Cup final for the first time is "crazy" and that his side is ready to once again play in extra time if needed.
Croatia beat 1966 champions England 2-1 on Thursday morning, with Mario Mandzukic netting the winner in the 109th minute after regulation time ended 1-1 in Moscow.
Croatia needed penalty shootouts to prevail over Denmark and hosts Russia in the previous two rounds of the knockout stage.
Corluka, who won the Russian Premier League title with Lokomotiv Moscow last season, has earned his 100th cap for Croatia at this summer's World Cup.
"They've already texted me from Lokomotiv. (Reaching the final) is an historic moment," said the 32-year-old.
"Nobody believed in this before the World Cup, but we are in the final - it's crazy. We are well-prepared. Croatia is now celebrating, and it gives us energy. We can play 120 minutes in the final, no problems, too."
Croatia, who claimed the third place at the 1998 FIFA World Cup, will take the winners of that tournament, France, in the final, which will be played at Moscow's Luzhniki Stadium on Monday morning.
