Roy Keane was confirmed as the assistant manager of Nottingham Forest on 28th January 2019. Previously to this, Keane also worked as Martin O'Neill's assistant manager for the Republic of Ireland.
Keane, the former Manchester United skipper - who won 12 major trophies in nine years at Old Trafford - achieved a whirlwind revolution at Sunderland in his first management job, where he guided The Black Cats to the Barclays Premier League.
Keane inherited a struggling side when he arrived at the Stadium of Light in late August, 2006. Sunderland were sitting second bottom after losing four of their first five games - but ended the season back in the Premier League. Title-winning Keane was subsequently voted the Championship's manager of the year.
He later managed Ipswich Town before he was appointed the assistant manager of Aston Villa combining his role with Ireland in July 2014. He remained with Villa until November of that year.
Born in Cork, Roy made it clear that he wished to continue in management and resurfaced at Ipswich in April, 2009. His new charges promptly won both their remaining matches. The highlight of his reign was guiding Ipswich to the semi-finals of the Carling Cup (only the fourth time in their history).
Keane was one of the top players of his generation, a dynamic and ferociously determined midfielder, who led by example. After losing two Wembley finals with Clough's Nottingham Forest, he became a serial winner with Ferguson at Manchester United.
Roy amassed seven Premiership titles, four FA Cups and the Champions League in the treble-winning year of 1999. It says much for his insatiable appetite that in 2000 he was voted player of the year by both the Football Writers Association and the PFA.
Besides a 66-cap career with the Republic of Ireland, Keane also achieved success in Scotland in the closing chapter of his playing days. He won the SPL title and the Scottish Cup with Celtic in 2006.
