The 22-year-old earns a return to Europe after a brief period abroad via Pacos de Ferreira in Portugal, where he did not make an appearance as he was loaned out to Casa Pia, Sanjoanense and Newcastle Jets between 2020 and 2022.

“I just want to say thank you very much to everyone at the Central Coast Mariners,” Silvera said. “We together created some unbelievable moments that I will never forget and will always cherish.

“I am just super happy that I could help be a part of an amazing achievement for the club and for the community. I will always love this club and it will always have special place in my heart. Until next time Mariners family.”

He joins forces with fellow Australian McGree, whose Boro lost in the semi-finals of the Championship play-offs in England’s second tier under Manchester United great Michael Carrick last season.

Silvera is the second Central Coast marvel to move to the North East of England after former Mariners teammate Nectarios Triantis joined Tees-Wear rivals Sunderland. The pair could potentially reunite when the two sides meet in the Championship on October 8 (AEST).

“For Sammy to have the opportunity to join a club like Middlesbrough is testament to the development of him both as a person and a player in such a short time,” said Mariners head coach Nick Montgomery.

“When we brought Sam back to the club he had been through a difficult few years of not playing many minutes of football and not really enjoying his football. I had no doubt of his potential and in the second half of the season he excelled and along with the other attacking players showed massive quality.

“As a club we are delighted for Sammy to provide him this pathway to Europe’s elite and to a club challenging for the Premier League.

“Sam had strong interest from a number of clubs around Europe and in Asia. Matt Simon negotiated offers around and in excess of Middlesbrough’s bid, but with Sammy’s desire to join the club and also be closer to his mum who lives in the UK, we worked together to make this happen. This move also shows the Mariners brand has become a real name around the world.”

It was a standout season for Silvera, who returned to Gosford for the 2022-23 campaign.

He caught the eye after scoring a career-high eight goals, including a goal in last month’s incredible 6-1 win over three-time reigning premiers Melbourne City in the Grand Final, and supplying five assists.

It was the Mariners’ first Championship in a decade.

Silvera’s move to Middlesbrough maintains their strong connection with Australia.


Aside from McGree, both he and Glover follow in the footsteps of Socceroos legends Mark Viduka, Mark Schwarzer, Scott McDonald, Rhys Williams, Brad Jones, Paul Okon, Tony Vidmar, Luke Wilkshire, Craig Johnston and Massimo Luongo to have played for the club.

Boro have not played in the Premier League since they were relegated at the end of the 2016-17 season.
