Kitchee can book their spot in the AFC Cup Round of 16 if they defeat Balestier, but Recio pointed out that advancing to the next round will be easier said than done.
"It is not going to be easy," he told the South China Morning Post. "We defeated Khalsa 3-0 at home, but playing away is a different ball game.
"We won't have the support of our fans, it will be very humid and the pitch is very different to what we are used to. It will be a tough match."
Despite having trained on the pitch and gotten accustomed to the conditions in Singapore, Recio confirmed that Kitchee will continue sticking to their usual tactics and "style of play".
"We trained on the pitch and it is very fast," he said. "But we will stick to our style of play, trying to keep possession.
"It is a really important match and if we win we enter the next round, which is our target for the moment."
However, even though he represented Kitchee in their 2-0 AFC Cup loss to Johor Darul Ta'zim on April 14, Recio admitted that he has not yet fully recovered from a foot injury he suffered earlier this year.
"I'm still not a 100 per cent, but I'm ready to go," he said. "This season, especially these past few weeks, has been amazing and a victory over Khalsa will continue that momentum."
