If their response to a lightning strike at training is anything to go by, Adelaide United have enough energy to face Perth Glory in Friday's A-League semi-final.
Adelaide's players may be fatigued after their A-League elimination final against Melbourne City but Marco Kurz knows there's enough energy left in his squad.
The speed with which players sought shelter after a lightning strike at their Hindmarsh base on Tuesday showed the Reds have gas in the tank for Friday's semi-final clash against premiers Perth.
"I was surprised by how quick they ran because in the training they looked a bit tired and slow but the sprint was very good, very fast," Kurz said.
Freshening up his players after their 120-minute effort against City is Kurz's biggest challenge as the Reds head west knowing they'll have to upset the odds to deny Glory a home grand final.
Adelaide will head to Perth a day earlier than normal with a 19-man squad to ensure they have as much recovery time as possible.
Kurz knows the odds are stacked against his team, given Glory will have had an 11-day break by the time Friday's match comes around.
"The advantage is with Perth because we have only five days rest, we have to travel - the flight, the time, distance - all of them it's not an advantage for us but Perth have worked really well to have this advantage," the German said.
"They've finished position one and that's the rewards in Australia."
Adelaide lost two of their three encounters with Glory this season and haven't scored against Tony Popovic's men.
Kurz, who will leave the Reds at the end of the season, isn't writing off extending his time at United for another week just yet, however.
"We are not the favourite, away in Perth, we are the underdog but that doesn't mean we're scared or we start very defensively," he said.
"We will find our chances and we can make a very good season maybe into a perfect one."
