Riera arrived in New Zealand six years ago intending to travel, but linked up with Auckland City through a contact in Spain. Three fruitful seasons at Kiwitea St followed, before his move to the Phoenix after impressing Ernie Merrick in a pre-season match.
Riera was the 2013-14 Phoenix Player of the Year and was picked for the A-League All Stars team to play Juventus. He become a crucial cog in the Wellington team, and shocked many observers when he asked for a release from the final year of his contract.
"It was a fantastic experience but it was the right time to go," he said. "I loved it. It was a dream to play professional football, but it is not an easy life, especially with all the travel. I needed a break from full-time football and didn't want to let anybody down."
Riera admits Merrick was initially surprised when he told him.
"We had a lot of mutual respect and I always wanted to be completely honest with him," said Riera. "If I felt that I wasn't able to give 100 per cent, then I knew it was time to go."
The 32-year-old played 68 games for the Phoenix across three seasons. Apart from the individual thrill of the All Stars game, Riera says the highlight of his time in Wellington was the 2014-15 season, when the team enjoyed an impressive run, especially across the Tasman, to finish fourth and make the A-League playoffs.
He is enjoying a new but familiar challenge at Auckland City, with December's trip to the Club World Cup in Japan already circled in the diary.
"That is a big challenge," said Riera. "We are looking forward to it. We have a fantastic squad and we are very motivated to do something special there."
