Jordan will play with 'one heart, one soul' in maiden Asian Cup final
Jordan are contesting their first final and in front of a partisan crowd at the 88,000-capacity Lusail Stadium in Doha will be the underdogs.
Jordan, who are 87 in the FIFA rankings compared to Qatar's 58, will be cheered on by a small but vocal group of their own supporters for the biggest game in the country's history.
The players' families have been flown in and Ajalin said that will help spur the team on as they look to pull off another shock, having defeated South Korea 2-0 in the semi-finals.
"We play with one heart, one soul, we are united," said Ajalin on Friday.
"Reaching the final is an achievement for everyone and it is nice to have our family with us and present in the audience."
Ajalin said that spirit of togetherness is one of the key reasons for Jordan's shock success.
"For us as players we work in a system from the goalkeeper all the way to the attack. We all work as one unit."
Jordan's Moroccan coach Hussein Ammouta said he will have a full squad to choose from, including the attackers Yazan Al-Naimat and Mousa Al-Tamari, who together gave the Korean defence a torrid time.
"All the players are up for it and ready," said Ammouta, adding "the match will be a technical one rather than a physical one".
Building on Ajalin's message of unity, Ammouta said: "The results of the team are because of the collaboration and effort of everyone.
"The players are committed and disciplined.
"But it is not just their fighting spirit. They follow the game plan to the letter."
