A devastated Jacques Faty and Mickael Tavares say losing Sunday's Hyundai A-League Grand Final might be the catalyst for them to stay at Sydney FC and win the title next year.

The pair signed for the Sky Blues during the Asian Cup break in January and have been key in the club's resurgence that took them all the way to the Grand Final.

WRAP: Victory outclass Sydney FC in Grand Final

The pair re-signing could be the one silver lining to a desperately disappointing performance from Sydney on the big day, losing 3-0 to a rampant Melbourne Victory in the season decider.

“My feeling is like, ‘I cannot leave this team and go by the little door’, Faty said, referring to leaving the club on the back of a loss in the Grand Final.

“I feel like very disappointed and I really want to stay here and make better for the next year. And next season. But I’m still thinking and must speak with all the people at the club.”

It’s understood there could be a decision on the French born Senegalese international pair this week.

Faty’s Sky Blue teammate and cousin – Mickael Tavares - agreed.

“I have the same feeling,” said Tavares.

“We came here on a mission. So we want to finish it. This year we didn’t get the title, so now we’re really thinking to stay to get it for the next season.”

Meanwhile, Faty’s hamstring injury forced him off in the first half at AAMI Park. It was a turning point in the decider, said Sydney coach Graham Arnold after the game.

“It was a horrible moment. I was really sorry to leave my teammates and partner,” said Faty, who estimated he’d be out for 10 days but is hopeful of playing against Spurs and Chelsea in Sydney in two weeks’ time.

“I had the objective of blocking Berisha today. And it was my job. Today he scored one goal. So when I left the pitch it was like a bad moment.

“I was dreaming about this a long time. Today my dream was like a nightmare.

“But next year we will do better.”
