We profile players who have played for both clubs.
JOHN OSTER (SAFC 1999-2005, RFC 2005-2008)
After a youth career at Grimsby Town and a spell at Everton, Oster made the move to the Stadium of Light in 1999. The winger enjoyed an eventful time at Sunderland, and struggled to hold down a regular first team place. He spent loan spells at Barnsley and Leeds as well as at former club Grimsby before being released in 2005. In all, Oster made almost 100 appearances for the Black Cats, scoring six goals in six years.
Oster moved to the Madejski after a short spell at Burnley. He was used mostly as a substitute in his time at the club, spending three years at the Royals. He made almost 50 sub appearances in league games, starting 29 matches. He was part of the side promoted to the Premier League at the end of the 2005/06 season and was part of their top flight squad for two seasons until their relegation in 2008, when he was released. He is currently plying his trade at League Two Barnet.
The name Ian Porterfield is written into Black Cats folklore as the man who secured the 1973 FA Cup. He moved to Wearside from Raith Rovers in 1967 and made over 200 appearances in the Sunderland first team. His most memorable moment was undoubtedly scoring the winning goal in Sunderland’s remarkable FA Cup win, beating favourites Leeds United in the final.
Porterfield enjoyed a brief loan spell at Reading towards the end of his Sunderland career, and also managed the side for 18 months from 1989 to 1991 in the old Third Division. After becoming the first manager to be sacked in the Premier League (at Chelsea in 1993), he had a number of international management roles, including spells at Zambia, Oman and Trinidad and Tobago. He was the coach of the Armenian national side in 2007 when he passed away, aged 61.
