Isaías insists Adelaide United must consolidate their momentum for the remainder of the campaign, after the Reds’ 3-2 victory over Central Coast Mariners in Gosford on Saturday.
Dylan McGowan’s header sandwiched between Baba Diawara’s brace extinguished the Mariners’ half-time lead.
The Reds delivered a strong second-half showing to score three goals in 10 minutes and jump off the bottom of the league table for the first time since Round 16.
“It’s fantastic, it’s a good feeling,” Isaías said.
“It’s nothing extraordinary, but for us at the moment I think it’s a good thing.”
The Reds are currently on a four-game unbeaten run in all competitions, and have scored eight goals in their past three fixtures.
While Adelaide cannot make the top six, Isaías said building momentum was crucial for the remainder of the AFC Champions League group stage.
“The good thing is we’re building momentum to arrive in the best possible form for our next Champions League game,” Isaías said.
“This is why we’re playing to win and also finish in the best possible position on the ladder.”
The Spaniard returned to the field after missing the Club’s last six matches due to a knee injury to make his 100th Hyundai A-League appearance.
The 30-year-old admitted he was a little nervous before kick-off, but said the apprehension disappeared once the opening whistle blew.
“I felt alright,” he said.
“I was a little bit scared at first with the tackles, not to get injured again.
“But I felt very good so I’m happy.”
Isaías also called for fans to flock to Coopers Stadium for its meeting with Perth Glory on Friday.
“We need the support from our fans to build momentum for our next Champions League game,” he continued.
“We need them to come to Coopers Stadium to support us.”
Adelaide United host Perth Glory in Round 25 of the Hyundai A-League 2016/17 season on Friday, 31 March at Coopers Stadium. Kick-off is at 7.20pm ACDT.
