The Brazilian has re-signed with the club on the back of a successful season, where he topped the scoring charts by notching up seven goals during the campaign.
His outstanding moment of the season came when he scored a brilliant hat-trick against Kerala Blasters in a 5-2 victory.
The 37-year-old joins the likes of Robin Singh in attack and will be expected to lead the charge again for the Goan club, for whom he made 10 appearances last season.
"I'm very happy to continue this journey with FC Goa. Last season, we had a very good campaign and fell marginally short. We want to take that extra step forward this year and go all the way.
"With Zico coming back, there is a familiarity to the setup once again and a certain comfort level with the rest of the team. The Goan crowds were a big influence on us last year and we are relying on the same continued support this season to help us achieve us goals. I'm looking forward to an intense pre-season campaign to get us ready for when the ball starts rolling," Reinaldo was quoted as saying.
Subhashish is a new signing, having plied his trade with Atletico De Kolkata in the past two seasons of the ISL. He was part of the squad that were crowned champions in the inaugural edition and was also involved in the second season before an injury curtailed his season.
He brings a wealth of experience with him and is expected to provide local boy Laxmikanth Kattimani with stiff competition for a place at the post.
The 29-year-old has been capped four times by the national team and is looking to use this season as a platform to regain his place.
A spokesperson for FC Goa said, "We are pleased to retain Reinaldo. Zico was impressed with his performances on the pitch last year and asked that he come back. Subhashish is also a great addition to the squad. We wanted to get a proven goalkeeper in and that's what we've got. We are happy with the composition of the squad so far and have some further signings to come."
